.ng is the Internet country code top-level domain (ccTLD) for Nigeria. It is overseen by the Nigeria Internet Registration Association (NIRA).
The top-level domain was first delegated in 1995 to Ibukun Odusote at the Yaba College of Technology. She was made a life patron of the Nigeria Internet Registration Association in 2013 for her work.
Operations were initially handled by an organization in Italy, the Instituto per le Applicazioni Telematiche (today known as the Istituto di Informatica e Telematica), but were later transferred to Randy Bush. In 2004, .ng was re-delegated in 2004 to a Nigerian organization, the National Information Technology Development Agency, and then in 2009, re-delegated to the Nigeria Internet Registration Association.
In addition, NIRA themselves reserve the right to register 'premium' top level domains under .ng (for example, "google.ng").
As of March 2022, there are 75 registrars accredited by NIRA. The most popular domain zone is .com.ng, having almost 70% of all national domains registered. The .ng domain comes next (17%) although within the zone a domain name is shorter, domain registration here costs several times more than in .com.ng while .org.ng, which is usually used by non-profit organisations, ranks third (7%).
