The Internet Corporation for Assigned Names and Numbers (ICANN) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (gTLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions. These services were originally performed under U.S. Government contract by the Internet Assigned Numbers Authority (IANA) and other entities. ICANN now performs the IANA function.
An IP address (Internet Protocol address) is a unique
number that devices use in order to identify and communicate with each
other on a computer network utilizing the Internet Protocol standard
(IP). Any participating network device - including routers, computers,
time-servers, printers, internet fax machines, and some telephones -
must have its own unique address.
An IP address can also be thought
of as the equivalent of a street address or a phone number for a
computer or other network device on the internet. Just as each street
address and phone number uniquely identifies a building or telephone,
an IP address can uniquely identify a specific computer or other
network device on a network.
