Number Resource Organization

Overview
The Number Resource Organization (NRO) is the coordinating body for the five Regional Internet Registries (RIRs) &mdashl AfriNIC, APNIC, ARIN, LACNIC and the RIPE NCC &mdash; that manage the distribution of Internet number resources, including IPv4 and IPv6 addresses and Autonomous System (AS) Numbers. Each RIR consists of the Internet community in its own region.
