Nononono, by network-wide I ment *MY* network not the Internet. :) Though
I really wouldn't mind seeing a well known community for "nexthop null0".
How can people sit around pontificating on useless features for useless

BTW, I don't know what announcing 127/8 would break since that should
never leave or enter any systems, and I still take issue with the need to
filter 1918 packets.
