An active participant in the Internet Engineering Task Force (IETF), he authored or coauthored several RFCs on addressing, including RFC2072, "Router Renumbering Guide." He recently published the book Designing Address Architectures for Routing and Switching, and will have another out shortly, Designing Routing and Switching Architectures for Enterprise Networks. Active in the North American Network Operators' Group (NANOG), he has given several talks on operationally critical aspects of addressing.
