I can confirm that indosat appears to be hijacking many prefixes. HE 6939 is one of the networks picking it up and distributing it further. Here's an example for a Syrian prefix: http://portal.bgpmon.net/data/indosat-hijack.png ==================================================================== Possible Prefix Hijack (Code: 10) ==================================================================== Your prefix: 5.0.0.0/18: Prefix Description: STE Public Data Network Backbone and LIR Update time: 2014-04-02 18:47 (UTC) Detected by #peers: 13 Detected prefix: 5.0.0.0/18 Announced by: AS4761 (INDOSAT-INP-AP INDOSAT Internet Network Provider,ID) Upstream AS: AS6939 (HURRICANE - Hurricane Electric, Inc.,US) ASpath: 271 6939 4761 Alert details: https://portal.bgpmon.net/alerts.php?details&alert_id=41644877 Mark as false alert: https://portal.bgpmon.net/fp.php?aid=41644877 Andree (BGPMON.net) .-- My secret spy satellite informs me that at 2014-04-02 11:59 AM Kate Gerry wrote:

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:
