Indeed! :) Just shows what good net.neighbours we humbuggers generally
are :)

You are right that alot of ppl forget the 172.16.0.0 - 172.31.255.255
range. In addition I have heard it said that 10.0.0.0/8 is often not as
secure - that alot of routers will let it sneak through, even when they
will block the other ranges. The range 10.0.0.0/8 was originally arpanet,
and as a result old h/w might not regard it as reserved IPspace at all.
Cheers,
