There is an old NANOG thread from 2005 that said AS 3356 (Level 3) were applying 3356:666 to indicate Peer route: https://archive.nanog.org/mailinglist/mailarchives/old_archive/2005-12/msg00280.html Also, see: https://onestep.net/communities/as3356/ Now network operators commonly use ASN:666 for BGP Blackholing Community. (ASN = the operator's AS number) See, for example, https://www.he.net/adm/blackhole.html Does anyone know if AS 3356 has changed how it uses 3356:666? I.e., is it known if they now use it for Blackholing Community? Thank you. Sriram
