Under the delegation of the Internet Assigned Numbers Authority (IANA), the InterNIC manages registrations of second-level domain names under the following top-level domains: EDU, GOV, COM, NET and ORG.
The InterNIC also assigns blocks of IP addresses to various entities. For example, the InterNIC allocates blocks of IP addresses to Internet Service Providers, who then distribute these IP addresses to their customers. Regional Network Information Centers such as APNIC (Asian-Pacific Network Information Center) and RIPE (Réseaux IP Européens) also receive blocks of IP addresses from the InterNIC for distribution in their regions.
