I compiled this list a few (6?) months ago by typing class A address
blocks into Arin.net's 'whois' web page and noting which Regional
Internet
Registry it was allocated to.

After plonking this into a couple of production hosts, attacks of all
ports dropped dramatically.
I note there have been changes since then (128.0.0.0 was assigned to RIPE
back in November), so if anybody wants to 'refresh' and post changes,
please do.
