A method and apparatus for ensuring network address uniqueness is described herein. An address manager determines whether any link-local addresses associated with peripheral devices connected to a mobile device would conflict with a network assigned global address. The address manager negotiates with the network to avoid conflicts.

Description

[0001] Priority claim under 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 075,127, filed June 24, 2008, entitled "Method and Apparatus for Ensuring IPv6 Uniqueness in a Mobile Subnetted Environment," assigned to the recipient of this application Almighty, is hereby incorporated by reference herein. technical field [0003] The present application relates generally to communications and, more particularly, to ensuring uniqueness of IP addresses when translating valid link-local IPv6 addresses into globally addressable IPv6 addresses. Background technique [0004] In an Internet Protocol (IP) network, a host communicates with another host through a router. In IP terminology, a "node" is an IP-implementing device, a "router" is a node that forwards IP packets not explicitly addressed to the router, and a "host" is a node that is not a router. As used herein, "IP" generally refers to all versions of the Internet Protocol. A ...
