On May 13, 2009, IANA (Internet Assigned Numbers Authority) completed the process of re-delegation of the .ng domain name from temporary authorities to the current Nigerian ones. For many years, Randy Bush had been the Technical contact of the .ng domain name. With the IANA re-delegation, the technical contact is now the local Nigerian DNS administrator, while the administrative contact is the president of Nigeria Internet Registration Association.
To speed up the process of registering .ng domain names, NIRA has accredited a first batch of 29 Domain registrars, most of whom are Nigerian companies. Registrars are categorized into Platinum, Gold, Silver and Standard categories.
Second level domains
In addition, NIRA themselves reserve the right to register 'premium' top level domains under .ng (for example, google.ng).
In January 2018 there were more than 60 registrars accredited by NIRA.  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%).
