Potential Prefix Hijack
Hi all. Anyone know how we can contact AS16735 and their upstream AS27664. We think they are hijacking a number of our prefixes (AS24218- and AS17992-originated). Thanks BGPmon: e.g., ==================== Possible Prefix Hijack (Code: 11) 1 number of peer(s) detected this updates for your prefix 18.104.22.168/20: Update details: 2008-11-11 02:24 (UTC) 22.214.171.124/20 Announced by: AS16735 (Companhia de Telecomunicacoes do Brasil Central) Transit AS: 27664 (CTBC Multimídia) ASpath: 27664 16735 ===================== RIPE's RIS BGPlay confirms the same, for about the last hour. E-mails to them won't get there (of course), so our NOC are contacting them via Gmail/Yahoo. All help appreciated. Cheers, Mark.
