The Internet Protocol Journal, Volume 13, No.1

From the Editor

Previous articles in IPJ have described Domain Name System Security Extensions (DNSSEC), the security system for the Domain Name System (DNS). DNSSEC introduces security into the DNS through the use of cryptographic keys and digital signatures. Interest in DNSSEC has grown in recent months, as the Internet Corporation for Assigned Names and Numbers (ICANN) and VeriSign have undertaken a phased program to deploy DNSSEC across the root server system in the first half of 2010. In an article by four DNS practitioners, we will explore some side effects of DNSSEC, and examine what happens in two widely used DNS resolver implementations when DNS clients lag behind in synchronizing their local copy of trust keys with the master keys used by the zone administrators to sign their DNS data.

Several articles in IPJ have dealt with various concerns related to scaling of the Internet. In this issue, Paul Francis and Xiaohu Xu describe Virtual Aggregation, a new routing technology being developed by the GROW working group of the IETF to reduce the size of the Forwarding Information Base (FIB) held in memory by routers.

The Request For Comments (RFC) Series has been the main publication channel for Internet standards and related documents for more than 40 years. The RFC Editor function is in the process of being restructured and moved from its original home at the University of Southern California Information Sciences Institute (USC/ISI). Leslie Daigle describes the history and future of the RFC Editor mechanism.
