I agree, ASN lookup in mtr would be awesome! I'll have to look into that sometime. Jason On Nov 30, 2013, at 19:58, Jason Lixfeld <jason@lixfeld.ca> wrote:
It would be slick if someone could patch mtr to do this too.

traceroute -A consults the internet routing registry which is know to beincomplete and at times incorrect when it comes to IP to BGP origin AS mapping. For this reason we developed riswhois.ripe.net, a whois style interface to the BGP data collected by RIPE NCC's Routing information service (http://www.ripe.net/data-tools/stats/ris)
Reporting in the same format as the IRR, riswhois is plugin compatible with whois.radb.net. If your linux traceroutederives from http://traceroute.sourceforge.net/ all it takes to switch to using true BGP info in traceroute is setting the environment variable RA_SERVER to "riswhois.ripe.net"

P.S. the LFT tool metioned earlier in this thread can also use RISwhois to lookup ASNs; just pass it the -r option on the command line.
