An Internet service provider (ISP) is an organization that provides access to the Internet.

An Internet service provider (ISP) is an organization that provides access to the Internet.

Internet service providers can be either community-owned and non-profit, or privately owned and for-profit.

Access ISPs directly connect clients to the Internet using copper wires, wireless or fiber-optic connections. Hosting ISPs lease server space for smaller businesses and other people (colocation). Transit ISPs provide large amounts of bandwidth for connecting hosting ISPs to access ISPs.

There are 3 tiers:

  • Tier 1: a tier 1 network is one that can reach every other network on the Internet without purchasing IP transit or paying settlements.
  • Tier 2: a tier that can access some part of the network without paying transit
  • Tier 3: only uses transit
