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So the half life of outdated bogon filters appears to be about 2.5 years, but if you really bug people like I did initially, you can make much better progress.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.
