Jon, could you tell Kawano san just how many sites are still blocking 69/8? :)
Number of IP's currently known to have 69/8 filter issues: 299 Number of /24 networks's currently known to have 69/8 filter issues: 261 And it's probably actually not that bad anymore. It seems a bunch of the IPs that were reachable from our old ARIN space but not 69/8 aren't reachable at all anymore. Back in late 2002 and early 2003 (when we got ours), 69/8 was much worse. Looking through the archives, it seems that first number was initially about 1000 when we got our 69 space, and when I announced http://69box.atlantic.net/ we had: Number of IP's currently known to have 69/8 filter issues: 683 Number of /24 networks's currently known to have 69/8 filter issues: 511 So the half life of outdated bogon filters appears to be about 2.5 years, but if you really bug people like I did initially, you can make much better progress. I basically picked the largest, most important looking networks and contacted them manually via email and phone. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

Someone already probably said this, but: route-views.oregon-ix.net>sho ip bgp 126.0.0.0/8 long | inc / * 126.0.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.1.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.2.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.3.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.20.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.21.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.64.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.66.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.68.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.69.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.70.0.0/16 206.24.210.26 0 3561 2914 17676 i * 126.71.0.0/16 206.24.210.26 0 3561 2914 17676 i

So, routeviews doesn't see the /8 are you sending it out as a /8?
