No. Those IP addresses will at least appear on traceroutes; also, it might not be such a good idea to use the same RFC1918 space (accidentally) on different IXPs. This will get your skin crawling (thing IGP, or at least config databases)... IXPs can usually get a v4 and a v6 block for their peering grid easily. > Can the IXP members use private autonomous numbers for their peering? They could, but what would you then do with them inside your IGP? And apart from that - ISPs that want to peer tend to have their ASNs ready... I am not an IXP operator, but I know of no exchange (public or private, big or closet-style) that uses private ASNs or RFC1918 space. Elmar.
