Based at Internet Corporation for Assigned Names and Numbers (ICANN), IANA is in charge of all “unique parameters” on the Internet, including Internet Protocol (IP) addresses. Each domain name is associated with a unique IP address, a numerical name consisting of four blocks of up to three digits each, e.g. 204.146.46.8, which systems use to direct information through the network.
