Early research and development:
45-498: Early research and development: Merging the networks and creating the Internet: Commercialization, privatization, broader access leads to the modern Internet: Examples of Internet services: UUNET Technologies, Inc. , formerly UUNET Communications Services , was an American commercial Internet service provider . Founded in 1987, it was one of the first and largest commercial ISPs and one of
90-409: A complex manner . From the perspective of server-side website deployment, there are two types of web pages: static and dynamic . Static pages are retrieved from the web server's file system without any modification, while dynamic pages must be created by the server on the fly , typically reading from a database to fill out a template , before being sent to the user's browser. An example of
135-672: A core network /backbone network; each subsequent network handles more traffic than the last. Mobile service providers also have similar networks. A mailbox provider is an organization that provides services for hosting electronic mail domains with access to storage for mail boxes. It provides email servers to send, receive, accept, and store email for end users or other organizations. Many mailbox providers are also access providers, while others are not (e.g., Gmail , Yahoo! Mail , Outlook.com , AOL Mail , Po box ). The definition given in RFC 6650 covers email hosting services , as well as
180-475: A telecommunications service, thereby preserving net neutrality. On 10 November 2014, President Barack Obama recommended that the FCC reclassify broadband Internet service as a telecommunications service in order to preserve net neutrality. On 16 January 2015, Republicans presented legislation, in the form of a U.S. Congress H.R. discussion draft bill , that makes concessions to net neutrality but prohibits
225-441: A tier 1 carrier . In reality, the situation is often more complex. ISPs with more than one point of presence (PoP) may have separate connections to an upstream ISP at multiple PoPs, or they may be customers of multiple upstream ISPs and may have connections to each one of them at one or more point of presence. Transit ISPs provide large amounts of bandwidth for connecting hosting ISPs and access ISPs. Border Gateway Protocol
270-902: A Tier 1 ISP. Transit ISPs may use OTN ( Optical transport network ) or SDH/SONET (Synchronous Digital Hierarchy/Synchronous Optical Networking) with DWDM ( Dense wavelength-division multiplexing ) for transmitting data over optical fiber. For transmissions in a metro area such as a city and for large customers such as data centers, special pluggable modules in routers, conforming to standards such as CFP , QSFP-DD, OSFP, 400ZR or OpenZR+ may be used alongside DWDM and many vendors have proprietary offerings. Long-haul networks transport data across longer distances than metro networks, such as through submarine cables, or connecting several metropolitan networks. Optical line systems and packet optical transport systems can also be used for data transmission. Ultra long haul transmission transports data over distances of over 1500 kilometers. A virtual ISP (VISP)
315-564: A commercial telecommunications market, such as the United States. In 1995, NSFNET was decommissioned removing the last restrictions on the use of the Internet to carry commercial traffic and network access points were created to allow peering arrangements between commercial ISPs. On 23 April 2014, the U.S. Federal Communications Commission (FCC) was reported to be considering a new rule permitting ISPs to offer content providers
360-400: A common domain name . The term "web page" is therefore a metaphor of paper pages bound together into a book. Each web page is identified by a distinct Uniform Resource Locator (URL). When the user inputs a URL into their web browser , the browser retrieves the necessary content from a web server and then transforms it into an interactive visual representation on the user's screen. If
405-467: A faster track to send content, thus reversing their earlier net neutrality position. A possible solution to net neutrality concerns may be municipal broadband , according to Professor Susan Crawford , a legal and technology expert at Harvard Law School . On 15 May 2014, the FCC decided to consider two options regarding Internet services: first, permit fast and slow broadband lanes, thereby compromising net neutrality; and second, reclassify broadband as
450-430: A large repository of software source code and related information. The venture proved successful and shed its non-profit status within two years. At the same time, the company changed its name to UUNET Technologies. In 1990, UUNET launched its AlterNet service, which provided access to an IP backbone independent of the constraints of those operated by the government. That network lives on in a much larger form and serves as
495-694: A number of other criteria an up to $ 30 per month discount toward internet service, or up to $ 75 per month on certain tribal lands. Access provider ISPs provide Internet access, employing a range of technologies to connect users to their network. Available technologies have ranged from computer modems with acoustic couplers to telephone lines, to television cable (CATV), Wi-Fi , and fiber optics. For users and small businesses, traditional options include copper wires to provide dial-up , DSL, typically asymmetric digital subscriber line (ADSL), cable modem or Integrated Services Digital Network (ISDN) (typically basic rate interface ). Using fiber-optics to end users
SECTION 10
#1732791068826540-514: A region. ISPs may engage in peering , where multiple ISPs interconnect at peering points or Internet exchange points (IXPs), allowing routing of data between each network, without charging one another for the data transmitted—data that would otherwise have passed through a third upstream ISP, incurring charges from the upstream ISP. ISPs requiring no upstream and having only customers (end customers or peer ISPs) are called Tier 1 ISPs . Network hardware, software and specifications, as well as
585-446: A tier 2 or tier 1 ISP usually has a larger network than the contracting ISP or is able to provide the contracting ISP with access to parts of the Internet the contracting ISP by itself has no access to. In the simplest case, a single connection is established to an upstream ISP and is used to transmit data to or from areas of the Internet beyond the home network; this mode of interconnection is often cascaded multiple times until reaching
630-557: A wide array of surveillance and packet sniffing equipment into their networks, which then feeds the data to law-enforcement/intelligence networks (such as DCSNet in the United States, or SORM in Russia) allowing monitoring of Internet traffic in real time. Web page A web page (or webpage ) is a document on the Web that is accessed in a web browser . A website typically consists of many web pages linked together under
675-534: Is an operation that purchases services from another ISP, sometimes called a wholesale ISP in this context, which allow the VISP's customers to access the Internet using services and infrastructure owned and operated by the wholesale ISP. VISPs resemble mobile virtual network operators and competitive local exchange carriers for voice communications. Free ISPs are Internet service providers that provide service free of charge. Many free ISPs display advertisements while
720-451: Is another option, including cellular and satellite Internet access . Access providers may have an MPLS ( Multiprotocol label switching ) or formerly a SONET backbone network , and have a ring or mesh network topology in their core network. The networks run by access providers can be considered wide area networks . ISPs can have access networks , aggregation networks/aggregation layers/distribution layers/edge routers/metro networks and
765-434: Is called Fiber To The Home or similar names. Customers with more demanding requirements (such as medium-to-large businesses, or other ISPs) can use higher-speed DSL (such as single-pair high-speed digital subscriber line ), Ethernet , metropolitan Ethernet , gigabit Ethernet , Frame Relay , ISDN Primary Rate Interface , ATM (Asynchronous Transfer Mode) and synchronous optical networking (SONET). Wireless access
810-482: Is done at IXPs, while private peering can be done with direct links between networks. Internet service providers in many countries are legally required (e.g., via Communications Assistance for Law Enforcement Act (CALEA) in the U.S.) to allow law enforcement agencies to monitor some or all of the information transmitted by the ISP, or even store the browsing history of users to allow government access if needed (e.g. via
855-576: Is used by routers to connect to other networks, which are identified by their autonomous system number. Tier 2 ISPs depend on Tier 1 ISPs and often have their own networks, but must pay for transit or internet access to Tier 1 ISPs, but may peer or send transit without paying, to other Tier 2 ISPs. Tier 3 ISPs do not engage in peering and only purchase transit from Tier 2 and Tier 1 ISPs, and often specialize in offering internet service to end customers such as businesses and individuals. Some organizations act as their own ISPs and purchase transit directly from
900-733: The Investigatory Powers Act 2016 in the United Kingdom ). Furthermore, in some countries ISPs are subject to monitoring by intelligence agencies. In the U.S., a controversial National Security Agency program known as PRISM provides for broad monitoring of Internet users traffic and has raised concerns about potential violation of the privacy protections in the Fourth Amendment to the United States Constitution . Modern ISPs integrate
945-505: The FCC from accomplishing the goal or enacting any further regulation affecting Internet service providers. On 31 January 2015, AP News reported that the FCC will present the notion of applying ("with some caveats") Title II (common carrier) of the Communications Act of 1934 to the Internet in a vote expected on 26 February 2015. Adoption of this notion would reclassify Internet service from one of information to one of

#1732791068826990-646: The Internet for a monthly fee, were established in Australia and the United States. In Brookline, Massachusetts , The World became the first commercial ISP in the US. Its first customer was served in November 1989. These companies generally offered dial-up connections, using the public telephone network to provide last-mile connections to their customers. The barriers to entry for dial-up ISPs were low and many providers emerged. However, cable television companies and
1035-668: The Internet. The FCC Chairman, Tom Wheeler , commented, "This is no more a plan to regulate the Internet than the First Amendment is a plan to regulate free speech. They both stand for the same concept." On 12 March 2015, the FCC released the specific details of the net neutrality rules. On 13 April 2015, the FCC published the final rule on its new " Net Neutrality " regulations. These rules went into effect on 12 June 2015. Upon becoming FCC chairman in April 2017, Ajit Pai proposed an end to net neutrality, awaiting votes from
1080-502: The UHF band (including the MMDS frequency band) and LMDS . It is hypothesized that the vast divide between broadband connection in rural and urban areas is partially caused by a lack of competition between ISPs in rural areas , where there exists a market typically controlled by just one provider. A lack of competition problematically causes subscription rates to rise disproportionately with
1125-482: The commission. On 21 November 2017, Pai announced that a vote will be held by FCC members on 14 December 2017 on whether to repeal the policy. On 11 June 2018, the repeal of the FCC's network neutrality rules took effect. Since December 31, 2021, The Affordable Connectivity Program has given households in the U.S. at or below 200% of the Federal Poverty Guidelines or households which meet
1170-431: The core of a set of products that include access at dial-up and broadband speeds as well as web hosting . UUNET raised $ 6 Million from Accel Partners, Menlo Ventures, and New Enterprise Associates in 1993 and $ 8.2 million in 1996 for expanding its network and hiring new executives with experience in marketing. In the mid-1990s, UUNET was the fastest-growing ISP, outpacing MCI and Sprint . At its peak, Internet traffic
1215-533: The difference in competition levels has potentially negatively affected the innovation and development of infrastructure in specific rural areas remains a question. The exploration and answers developed to the question could provide guidance for possible interventions and solutions meant to remedy the digital divide between rural and urban connectivity. Altnets (portmanteau of "alternative network provider") are localized broadband networks, typically formed as an alternative to monopolistic internet service providers within
1260-496: The e-mail addresses for moderated Usenet groups, it was hard to block email traffic to or from Usenet. In 1997, UUNET had lost so much credit that on 1 August, after finding alternate routes for moderated newsgroups, a Usenet death penalty (UDP) was issued against UUNET. A week later, the UDP was lifted. In 1998 UUNET threatened legal action for hosting a GIF image with "SPAMUNET" on it. Internet service provider Merging
1305-533: The early Tier 1 networks . It was based in Northern Virginia . Today, UUNET is an internal brand of Verizon Business (formerly MCI ). Prior to its founding, access to Usenet and e-mail exchange from non- ARPANET sites was accomplished using a cooperative network of systems running the UUCP protocol over POTS lines. During the mid-1980s, growth of this network began to put considerable strain on
1350-400: The expertise of network management personnel are important in ensuring that data follows the most efficient route, and upstream connections work reliably. A tradeoff between cost and efficiency is possible. Tier 1 ISPs are also interconnected with a mesh network topology. Internet Exchange Points (IXPs) are public locations where several networks are connected to each other. Public peering
1395-477: The introduction of the World Wide Web . During the 1980s, online service providers such as CompuServe , Prodigy , and America Online (AOL) began to offer limited capabilities to access the Internet, such as e-mail interchange, but full access to the Internet was not readily available to the general public. In 1989, the first Internet service providers, companies offering the public direct access to

1440-524: The name was dropped from all official documents. In 2002, the owner of UUNET at that time (WorldCom) filed for what was then the largest Chapter 11 bankruptcy protection in history. In 2005, its Internet service and infrastructure, assigned AS 701, maintained the highest outdegree of any ISP. In 2006, WorldCom was purchased by Verizon Communications and now operates under the Verizon Business name. After it had been sold and resold during
1485-705: The networks and creating the Internet: Commercialization, privatization, broader access leads to the modern Internet: Examples of Internet services: An Internet service provider ( ISP ) is an organization that provides myriad services related to accessing, using, managing, or participating in the Internet . ISPs can be organized in various forms, such as commercial, community-owned , non-profit , or otherwise privately owned . Internet services typically provided by ISPs can include internet access , internet transit , domain name registration, web hosting , and colocation . The Internet (originally ARPAnet )
1530-420: The onset of the dot-com bubble , UUNET acquired the nickname SpewSpewNET . This nickname was given because UUNET had become a home for many distributors of spam , including distributors of both Newsgroup spam and E-mail spam . UUNET also became known for providing bulletproof hosting to many web pages whose chief form of advertisement was spam. Because UUNET started with a loan from Usenix and controlled

The vast majority of pages have JavaScript programs , enabling a wide range of behavior. The newer WebAssembly language can also be used as a supplement . The most sophisticated web pages, known as web apps , combine these elements in
1620-415: The quality of service in rural areas, causing broadband connection to be unaffordable for some, even when the infrastructure supports service in a given area. In contrast, consumers in urban areas typically benefit from lower rates and higher quality of broadband services, not only due to more advanced infrastructure but also the healthy economic competition caused by having several ISPs in a given area. How
1665-764: The relevant department of companies, universities, organizations, groups, and individuals that manage their mail servers themselves. The task is typically accomplished by implementing Simple Mail Transfer Protocol (SMTP) and possibly providing access to messages through Internet Message Access Protocol (IMAP), the Post Office Protocol , Webmail , or a proprietary protocol. Internet hosting services provide email, web-hosting, or online storage services. Other services include virtual server , cloud services, or physical server operation. Just as their customers pay them for Internet access, ISPs themselves pay upstream ISPs for Internet access. An upstream ISP such as
1710-514: The resources voluntarily provided by the larger UUCP hubs . This prompted Rick Adams , a system administrator at the Center for Seismic Studies, to explore the possibilities of providing these services commercially as a way to reduce the burden on the existing hubs. With funding in the form of a loan from Usenix , UUNET Communications Services began operations in 1987 as a non-profit corporation providing Usenet feeds, e-mail exchange, and access to

The FCC was expected to enforce net neutrality in its vote, according to The New York Times . On 26 February 2015, the FCC ruled in favor of net neutrality by adopting Title II (common carrier) of the Communications Act of 1934 and Section 706 in the Telecommunications Act of 1996 to
1800-427: The telephone carriers already had wired connections to their customers and could offer Internet connections at much higher speeds than dial-up using broadband technology such as cable modems and digital subscriber line (DSL). As a result, these companies often became the dominant ISPs in their service areas, and what was once a highly competitive ISP market became effectively a monopoly or duopoly in countries with

Other free ISPs, sometimes called freenets , are run on a nonprofit basis, usually with volunteer staff. A wireless Internet service provider (WISP) is an Internet service provider with a network based on wireless networking. Technology may include commonplace Wi-Fi wireless mesh networking, or proprietary equipment designed to operate over open 900 MHz, 2.4 GHz, 4.9, 5.2, 5.4, 5.7, and 5.8 GHz bands or licensed frequencies such as 2.5 GHz (EBS/BRS), 3.65 GHz (NN) and in
1935-413: Was an independent acquisition unrelated to the acquisition of MFS by WorldCom. However, as MFS was a public company and the acquisition made the company a Wall Street darling, it likely influenced WorldCom's decision to pursue MFS. In 1996, UUNET was acquired by WorldCom on 26 August 1996, as part of WorldCom's purchase of MFS Communications Company. In 2001, UUNET was fully integrated with WorldCom and
1980-413: Was briefly doubling every few months, which translates to 10x growth each year. However, the continuing UUNET claims of such growth (long after it had fallen to lower, albeit still substantial levels) artificially fueled the expectations of the dot-com and telecom companies of the late 1990s, leading to the dot-com bubble and crash in 2000/2001. In 1996, UUNET was acquired by MFS on 30 April 1996. This
2025-443: Was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations joined by direct connection to the backbone , or by arrangements through other connected companies, sometimes using dialup tools such as UUCP . By the late 1980s, a process was set in place towards public, commercial use of the Internet. Some restrictions were removed by 1991, shortly after
