There's a paper on just this problem from SIGCOMM 2003:

I want to create a mapping of IP addresses to ASN, for a specific like
of IP addresses. Eg:
1.2.3.4
12.34.56.78

etc, gathered from my system logs.

What is the best way of doing this?

I thought about something along the lines of:
install routing software (zebra?)
pass software the IP's, get it to spit back a string from which I can
grab the ASN

Two problems being I don't know which software to install that can do
that, or where to get a copy of the current routing table, so that I can
feed that to the software.

Suggestions appreciated.
