ICANN (Internet Corporation for Assigned Names and Numbers)
The Internet Corporation for Assigned Names and Numbers (ICANN) is a
nonprofit private organization headquartered in the Playa Vista section
of Los Angeles, California, United States. It was created on September
18, 1998, and incorporated on September 30, 1998 to oversee a number of
Internet-related tasks. This was previously performed directly on behalf
of the U.S. government by other organizations, notably the
Internet Assigned Numbers Authority (IANA), which ICANN now operates.
ICANN is responsible for the coordination of the global Internet's
systems of unique identifiers and, in particular, ensuring its stable
and secure operation. This work includes coordination of the Internet
Protocol address spaces (IPv4 and IPv6) and assignment of address blocks
to regional Internet registries, for maintaining registries of Internet
protocol identifiers, and for the management of the top-level domain
name space (DNS root zone). This includes the operation of root name
servers. ICANN performs the actual technical maintenance work of the
central Internet address pools and DNS root registries pursuant to the
"IANA function" contract.
