Abstract

In the near future GPS will be widely used allowing a broad variety of location dependent services such as direction giving, navigation, etc. In this document we propose a family of protocols and addressing methods to integrate GPS into the Internet Protocol to enable the creation of location dependent services such as:

GPS-Based Addressing and Routing

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.
