Technology advances—such as improvements in display technology, battery life, processor capabilities, and communications systems—have all contributed to making mobile devices the most important area for Internet growth. In order to fully support these devices, the IETF developed Mobile IP many years ago, and it has continued to work on the general area of IP mobility. We have covered some of this work in previous issues of IPJ, and this time we look at Proxy Mobile IPv6 (PMIPv6), which is being standardized by the IETF. The article is by Ignacio Soto, Carlos J. Bernardos, María Calderón, and Telemaco Melia.
Deployment of IPv6 is progressing, albeit slowly. In several upcoming articles we will examine some transition technologies or implementation details that can make this deployment easier, and above all, transparent, to the end user. In our first article, Dan Wing and Andrew Yourtchenko explain the concept of "Happy Eyeballs" as applied to dual-stack IPv4/IPv6 systems.
Domain Name System Security Extensions (DNSSEC) have recently been applied to the Internet system of root servers. For details, see our "Fragments" section, where you will also find a statement from the Number Resource Organization (NRO) regarding the results of a recent IPv6 readiness study.
