The .ao top-level domain is designated for use to represent Angola and is currently managed by the Ministry of Telecommunications and Information Technologies (MTTI).
It was managed by the Faculdade de Engenharia da Universidade Agostinho Neto (FCCN) beginning in in the mid-1990s.
In February 2000, Fundação para a Computação Científica Nacional (FCCN), the organization responsible for the management of the .pt (Portugal) top-level domain, began providing technical services for the .ao top-level domain and was listed as its technical contact in the IANA Root Zone Database.
In May 2013, after a restructuring of FCCN's mission and responsibilities, a new entity named Associação DNS.PT (DNS.PT) was created to manage the .pt top-level domain and provide technical services for several other ccTLDs, including .ao.
In October 2014, the IANA Root Zone Database was updated to reflect the .ao technical contact change to DNS.PT.
On 25 January 2018, through Presidential Decree No. 16/18, the mission of the MTTI was established as the entity responsible for the policy and strategy of telecommunications and information technologies in Angola.
On 21 August 2018, Presidential Decree No. 107/18 approved the transfer of the management and operation of the .ao top-level domain to the MTTI.
On 1 October 2018, MTTI Decree No. 4820 created a working committee for transferring management of the .AO top-level domain to MTTI in order to “strengthen the security and protection of the digital sovereignty of the Angolan State in cyberspace, with technical and administrative measures”. The committee was coordinated by Manuel Gomes da Conceição Homem, the proposed administrative contact, and composed of five members including the General Secretary, the Director of the Legal Office, the National Director of Telecommunications, the National Director of the Information Society and Meteorology and the Director of the National Institute for the Development of the Information Society.
