I received a similar notification about one of our prefixes also a few minutes ago. I couldn't find a looking glass for AS4761 or AS4651. But I also couldn't hit the websites for either AS, either. Frank -----Original Message----- From: Joseph Jenkins [mailto:joe@breathe-underwater.com] Sent: Wednesday, April 02, 2014 1:52 PM To: nanog@nanog.org Subject: BGPMON Alert Questions So I setup BGPMON for my prefixes and got an alert about someone in Thailand announcing my prefix. Everything looks fine to me and I've checked a bunch of different Looking Glasses and everything announcing correctly. I am assuming I should be contacting the provider about their misconfiguration and announcing my prefixes and get them to fix it. Any other recommendations? Is there a way I can verify what they are announcing just to make sure they are still doing it? Here is the alert for reference: Your prefix: 8.37.93.0/24: Update time: 2014-04-02 18:26 (UTC) Detected by #peers: 2 Detected prefix: 8.37.93.0/24 Announced by: AS4761 (INDOSAT-INP-AP INDOSAT Internet Network Provider,ID) Upstream AS: AS4651 (THAI-GATEWAY The Communications Authority of Thailand(CAT),TH) ASpath: 18356 9931 4651 4761
