A Virtual ISP (VISP), also known as an Affinity ISP, is an Internet service provider (ISP) that resells the resources of existing ISPs under another brand name.
A Virtual ISP (VISP) purchases services from another ISP (sometimes called a wholesale ISP or similar within this context) that allow the VISP's customers to access the Internet via one or more Points of Presence (PoPs) that are owned and operated by the wholesale ISP.
Virtual ISPs can vary from a normal ISP buying access points off a third party to a complete white label service where the branding of the VISP is usually such as to portray the image of being an ISP in their own right.
There are various models for the delivery of Virtual ISPs. As an example a wholesale ISP could provide network access to end users via its dial-up modem PoPs or DSLAMs installed in telephone exchanges, and route, switch, and/or tunnel the end-user traffic to the VISP's network, whereupon they may route the traffic toward its destination.
In another model, the wholesale ISP does not route any end-user traffic, and needs only provide AAA (Authentication, Authorization and Accounting) functions, as well as any value-add services, like email or web hosting.
A complete VISP will consist of a pure rebranding of another ISP offering where the host ISP manages all aspects of the service. This model is commonly used for charities and other affinity organisations where 'MyOrganisation' ISP is actually a virtual service on another ISP.
Any given ISP may use their own PoPs to deliver one service, and use a VISP model to deliver another service, or, use a combination to deliver a service in different areas.
The service provided by a wholesale ISP in a VISP model is distinct from that of an upstream ISP, even though, in some cases, they may both be one and the same company. The former provides connectivity from the end-user's premises to the Internet or to the end-user's ISP, and the latter provides connectivity from the end user's ISP to all or parts of the rest of the Internet.
A VISP can also be a dial-up white label service offered to anyone at no cost or for a minimal setup fee. The actual ISP providing the service generates revenue from the calls and may also share a percentage of that revenue with the owner of the VISP. All technical aspects are dealt with, leaving the owner of VISP with the task of promoting the service. This sort of service is, however, declining due to the popularity of unmetered dial-up access.
The world's first Virtual ISP was pioneered by the UK arm of the Canadian Intasys Corporation [1] (now Ace*Comm) in partnership with Easynet. Called 'Intasys Online' the VISP was launched in London in 1996 and was used primarily as a demonstration ISP for other virtual ISPs. Intasys operated successfully as a branded ISP provider providing virtual ISPs for clients until the internet arm was sold to Zygo Productions in 1998.
A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet.
The Internet backbone is the principal data routes between large, strategically interconnected computer networks and core routers of the Internet. These data routes are hosted by commercial, government, academic and other high-capacity network centers as well as the Internet exchange points and network access points, which exchange Internet traffic internationally. Internet service providers (ISPs) participate in Internet backbone traffic through privately negotiated interconnection agreements, primarily governed by the principle of settlement-free peering.
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.
A web hosting service is a type of Internet hosting service that hosts websites for clients, i.e. it offers the facilities required for them to create and maintain a site and makes it accessible on the World Wide Web. Companies providing web hosting services are sometimes called web hosts.

At the retail level, many organizations, including municipal entities, also provide cost-free access to the general public.

A content delivery network or content distribution network (CDN) is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and performance ("speed") by distributing the service spatially relative to end users. CDNs came into existence in the late 1990s as a means for alleviating the performance bottlenecks of the Internet as the Internet was starting to become a mission-critical medium for people and enterprises. Since then, CDNs have grown to serve a large portion of the Internet content today, including web objects, downloadable objects, applications, live streaming media, on-demand streaming media, and social media sites.

Net bias is the counter-principle to net neutrality, which indicates differentiation or discrimination of price and the quality of content or applications on the Internet by ISPs. Similar terms include data discrimination, digital redlining, and network management.
A secure access service edge (SASE) is technology used to deliver wide area network (WAN) and security controls as a cloud computing service directly to the source of connection rather than a data center. It uses cloud and edge computing technologies to reduce the latency that results from backhauling all WAN traffic over long distances to one or a few corporate data centers, due to the increased movement off-premises of dispersed users and their applications. This also helps organizations support dispersed users.
