i wondered the same thing. here's what i see at mae-east being announed by some (i filter): deny ip 10.0.0.0 0.255.255.255 255.0.0.0 0.255.255.255 (227 matches) deny ip 192.0.0.0 0.0.0.255 255.255.255.0 0.0.0.255 (603 matches) deny ip 198.32.146.0 0.0.0.255 255.255.255.0 0.0.0.255 (543 matches) deny ip 198.32.176.0 0.0.0.255 255.255.255.0 0.0.0.255 (10 matches) deny ip 192.157.69.0 0.0.0.255 255.255.255.0 0.0.0.255 (96 matches) deny ip 198.32.128.0 0.0.0.255 255.255.255.0 0.0.0.255 (335 matches) ya, ya, teh last four aren't rfc1918 but i filter them anyway (nap dmz's) :) lot's of people announcing them. the first two are the only rfc1918 nets i see announced on our nap routers. -brett

Why aren't people actively filter on RFC1918 announcements??
