Udo,
 I don't know how to respond to this. You are so far
off track, just to keep an argument going, that it
is just not worth it. There is just too much weird
BS in there. If you want to feel like you've won an
argument, or got the last word, go for it. I'm done
with this nonsense.

Udo,
 I wasn't referring to modems negotiating speed and
protocol on a new connection, but the routing of data
packets across the 'net. Routers use a timed update
of all available routers and keep this info in their
routing tables.

Are you saying that the routers ignore IP addresses completely? Well,
that would be a wonderful thing, and most certainly the solution to the
problem with scarce addresses in an IPV4 network! ;-)

So tell me, how do the routers react if a packet is sent back to the
forged address? Do they really know where to send it even though the
address says that it belongs to the Asian region? ;-D

Mind that we are not talking about gateways to an isolated net here,
which are also commonly referred to as "routers", and which regularly do
NAT, but about servers whose sole purpose is to route the packets to
their destination in as few "hops" as possible. Would they really send
the packet to the router that the forged address came from even though
it does not match the corresponding sub net mask? About the only purpose
of the sub net mask is to make the routing of packets to the right sub
net easier, and you just say the Internet routers ignore it? I can't
believe this.

Regards,

Udo
