The Internet Computer Bureau is an Internet top-level domain custodian based in the United Kingdom. The custodian is responsible for maintaining the .io, .sh, and .ac country code top-level domains.[1] In 2017 it became a subsidiary of Afilias, a United States corporation.
The company was established in 1996 as Internet Computer Bureau plc, and became a private limited company in 2004.[2]
Embroiled in controversy around its involvement in registration of .io domains associated with the Diego Garcia military base following the expulsion of the Chagossian population,[3] ICB was sold by Paul Kane to Afilias for $70 million in April 2017.[4]
