About .aero domains
.AERO is a top-level domain delegated in the IANA root zone. See the official IANA delegation record for manager and technical contacts.
.aero (derived from aeronautics) is a sponsored top-level domain (sTLD) used in the Domain Name System of the Internet. It is the first sponsored top-level domain based on a single industrial theme. The .aero domain is reserved for companies, organizations, associations, government agencies, and individuals in aerospace-related fields. It was created in 2002 and is operated by SITA. SITA created and operates the Dot Aero Council. Two-letter codes under .aero are reserved for airlines according to the IATA Airline Designators. While three-letter codes were initially reserved for airports (IATA airport code), they were released for registration by the larger aviation and aerospace community on December 1, 2008. The aero top-level domain was initially approved in 2001 for a 5-year term expiring December 17, 2006 as part of a proof-of-concept of new top-level domains. The agreement was extended in October 2006 for a six-month term until June 17, 2007, and continued to be renewed on a June–December six-month cycle through June 17, 2009. In 2009, SITA and ICANN completed a new 10-year sponsorship agreement for the operation of .aero.
