A Waypoint Service Approach to Connect Heterogeneous Internet Address Spaces

The rapid growth of the Internet has made IP addresses a scarce resource. To get around this problem, today and in the foreseeable future, networks will be deployed with reusable-IP addresses (a.k.a. private-IP addresses) or IPv6 addresses. The Internet is therefore evolving into a collection of networks of heterogeneous address spaces. Such development jeopardizes the fundamental bi-directional connectivity property of the Internet.
