astraceroute is based on traceroute from LBL
(
ftp://ftp.ee.lbl.gov/traceroute.tar.gz) with the added feature of
origin AS resolution, much like the prtraceroute that comes with the
IRRToolSet.
prtraceroute uses the IRR for AS resolution, but the IRR data is often
out-of-date or missing entirely. astraceroute resolves the origin AS
by DNS resolution of the IP address in the time-execeeded reply via the
asn.routeviews.org domain (
www.routeviews.org).
A traceroute to nic.near.net, for example:
% astraceroute -a nic.near.net

of the IP.
