Status of this Memo
This memo defines an Experimental Protocol for the Internet
community. This memo does not specify an Internet standard of any
kind. Discussion and suggestions for improvement are requested.
Distribution of this memo is unlimited.
IANA Note:
This document describes a possible experiment with geographic
addresses. It uses several specific IP addresses and domain names in
the discussion as concrete examples to aid in understanding the
concepts. Please note that these addresses and names are not
registered, assigned, allocated, or delegated to the use suggested
here.
