Hi,
The attached patch ports a traceroute functionality from FreeBSD
called AS path.
The concept is simple. On each hop we query a whois server to find
the
corresponding hop AS number.
I think it doesn't hurt if we have this functionality.
An example output:
traceroute to freebsd.org (69.147.83.40), 64 hops max, 72 byte
packets

What do you think?
Would it be difficult to add it to traceroute6 too? It would be great
if we can keep features in sync.
I will try to do it after committing this patch.
Regards.
