 The increasing cultural diversity of the Internet also posed administrative challenges for centralized management of the IP addresses.In October 1992, the Internet Engineering Task Force (IETF) published RFC 1366, which described the "growth of the Internet and its increasing globalization" and set out the basis for an evolution of the IP registry process, based on a regionally distributed registry model.This document stressed the need for a single Internet number registry to exist in each geographical region of the world (which would be of "continental dimensions").
