There's a paper on just this problem from SIGCOMM 2003: http://www.acm.org/sigcomm/sigcomm2003/papers.html#p365-mao On Thursday, Oct 9, 2003, at 09:49 US/Pacific, Avleen Vig wrote:
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.
