This document reports the outcome of the Routing and Addressing
Workshop that was held by the Internet Architecture Board (IAB) on
October 18-19, 2006, in Amsterdam, Netherlands. The primary goal of
the workshop was to develop a shared understanding of the problems
that the large backbone operators are facing regarding the scalability
of today's Internet routing system. The key workshop findings
include an analysis of the major factors that are driving routing
table growth, constraints in router technology, and the limitations of
today's Internet addressing architecture. It is hoped that these
findings will serve as input to the IETF community and help identify
next steps towards effective solutions. Note that this document is a
report on the proceedings of the workshop. The views and positions
documented in this report are those of the workshop participants and
not of the IAB. Furthermore, note that work on issues related to this
workshop report is continuing, and this document does not intend to
reflect the increased understanding of issues nor to discuss the range
of potential solutions that may be the outcome of this ongoing work.
