Information about the geographic locality of IP prefixes can be useful
for understanding the issues related to IP
address allocation, aggregation, and BGP routing table growth.
In this paper, we use traceroute data and geographic mappings of IP
addresses to study the geographic properties of IP prefixes and their
implications on Internet routing. We find that
(1) IP prefixes may be too coarse-grained
for expressing routing policies,
(2) address allocation policies and the granularity of
routing contribute significantly to
routing table size, and (3) not considering the
geographic diversity of contiguous prefixes may result in
overestimating the opportunities for aggregation in the BGP routing
table.
