Internet Service Provider (ISP) – What It Is and How to Choose the Best – An Internet Service Provider (ISP) is an organization that provides services for accessing, using, managing, or participating in the Internet. ISPs can be organized in various forms, such as commercial, community-owned, non-profit, or privately owned. ISPs provide internet access through various means, including dial-up, DSL, cable, wireless, and fiber-optic connections.
In addition to internet access, ISPs may provide other services such as email, domain registration, web hosting, and browser services. ISPs act as gateways that allow users to connect to their network and access the internet using web-enabled devices.

History of ISPs
The Internet (originally ARPANET) was developed as a network between government research laboratories and participating departments of universities. Other companies and organizations are joined by direct connection to the backbone, or by arrangements through other connected companies, sometimes using dial-up tools such as UUCP. By the late 1980s, a process was set in place for public, commercial use of the Internet. Some restrictions were removed by 1991, shortly after the introduction of the World Wide Web.
During the 1980s, online service providers such as CompuServe 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 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 number of ISPs increased to several thousand during the mid-1990s, and the boom was on. As the options for connectivity increased and speeds moved away from slower dial-up connections, the internet economy was born. Providers developed more advanced technology, allowing customers high-speed access via broadband technology through cable and digital subscriber line (DSL) modems.
Behind all of this was a multilayered web of connections. Local ISPs sold access to customers but paid larger ISPs for their own access. These larger ISPs, in turn, paid even larger ISPs for access. The trail leads to Tier 1 carriers that can reach every network access point without having to pay for access. These Tier 1 companies own the infrastructure in their region.
Internet service providers provide their customers access to the internet—plain access providers just handle the traffic between the individual and the internet as a whole. But there may also be other services bundled in depending on the customer’s location and availability.
Types of ISPs
ISPs can be classified into different types based on the services they offer and the technologies they use. Some common types of ISPs are:
- Access providers: These are ISPs that provide internet access to users through various means, such as dial-up, DSL, cable modem, wireless or fiber-optic connections. They may also offer other services such as email accounts and web hosting.
- Hosting ISPs: These are ISPs that provide web hosting services for websites and applications. They may also offer domain name registration and email hosting.
- Transit ISPs: These are ISPs that provide internet transit services to other ISPs or large networks. They usually have high-bandwidth connections to multiple Tier 1 networks and charge fees based on traffic volume or bandwidth usage.
- Virtual ISPs: These are ISPs that resell internet services from another ISP without owning any network infrastructure or equipment. They may offer lower prices or customized plans to customers.
- Free ISPs: These are ISPs that provide free internet access to users in exchange for displaying advertisements or collecting user data. They may have limited features or quality compared to paid ISPs.
- Wireless ISPs: These are ISPs that provide wireless internet access to users through radio waves or satellite signals. They may use Wi-Fi hotspots, cellular networks or fixed wireless technologies.
Functions of ISPs
ISPs perform various functions to enable users to access and use the internet. Some of these functions are:
Routing
This is the process of directing data packets from one network node to another based on their destination addresses. ISPs use routers and switches to route data packets across their networks and interconnect with other networks.
Addressing
This is the process of assigning unique identifiers to network devices and hosts on the internet. ISPs use IP addresses and domain names to identify and locate network resources on the internet.
Caching
This is the process of storing frequently accessed data in local servers or devices to reduce bandwidth consumption and improve performance. ISPs use caching servers or proxy servers to cache web pages, images, and other content for faster delivery to users.
Filtering
This is the process of blocking or allowing data packets based on their source, destination, content, or protocol. ISPs use firewalls, content filters, or traffic shapers to filter data packets for security, privacy, or quality of service reasons.
Peering
This is the process of exchanging data traffic between ISPs without charging fees. ISPs use peering agreements and internet exchange points to peer with other ISPs and reduce transit costs and latency.
Security
This is the process of protecting network devices, hosts, and data from unauthorized access, modification, or damage. ISPs use encryption, authentication, authorization, and other security measures to secure their networks and services.
Challenges and Issues Facing ISPs
ISPs face various challenges and issues in providing internet services to users. Some of these are:
Competition
ISPs compete with each other for customers, market share, and revenue. They have to offer competitive prices, plans, features, and quality to attract and retain customers. They also have to deal with new entrants, such as over-the-top (OTT) service providers, that offer internet-based services such as video streaming, voice calling, and messaging without using ISP networks.
Regulation
ISPs are subject to various regulations and laws that affect their operations and services. They have to comply with rules and standards regarding licensing, taxation, privacy, security, net neutrality, censorship, and consumer protection. They also have to deal with legal disputes and complaints from customers, authorities, or other parties.
Innovation
ISPs have to keep up with the rapid changes and developments in the internet industry. They have to invest in new technologies, equipment, and infrastructure to improve their networks and services. They also have to adapt to changing customer needs, preferences, and behaviors.
Costs
ISPs incur various costs in providing internet services to users. They have to pay for network infrastructure, equipment, maintenance, bandwidth, transit, peering, personnel, and other expenses. They also have to deal with rising costs due to increasing demand, competition, and regulation.
Future of ISPs
ISPs play a vital role in the internet ecosystem and society. They will continue to provide internet services to users in the future, but they may face some changes and challenges as well. Some possible trends and scenarios for the future of ISPs are:
Consolidation
ISPs may merge or acquire each other to increase their market power, reduce costs and improve efficiency. They may also form alliances or partnerships with other players in the internet industry, such as OTT service providers, content providers, or device manufacturers.
Diversification: ISPs may diversify their services and offerings to increase their revenue streams and customer loyalty. They may offer more value-added services, such as cloud computing, e-commerce, online gaming, or IoT solutions. They may also target different segments or niches of customers, such as businesses, rural areas, or low-income groups.
Disruption
ISPs may face disruption from new technologies or business models that challenge their dominance or relevance. They may have to compete with alternative internet access methods, such as mesh networks, peer-to-peer networks, or satellite networks. They may also have to deal with new forms of competition or regulation that affect their profitability or viability.
