you'd be surprised... i've learnt (the hard way) you should NEVER EVER
assume anything about end users :)

not really... i think you'll find that 192.168.0.* is part of the
"universally accepted IP range for private home networks".... or to put
it another way... its what it says in the windows help files :)

Numbering your network
For private TCP/IP networks that are not directly or indirectly
connected to the Internet, you can use any range of valid IP addresses
from Class A, B, or C.

For private TCP/IP networks that are indirectly connected to the
Internet by using a network address translator (NAT) or an application
layer gateway such as a proxy server, the Internet Assigned Numbers
Authority (IANA) recommends that you use the private IP addresses shown
in the following table.

Private netID Subnetmask IP Range
10.0.0.0 255.0.0.0 10.0.0.1 - 10.255.255.254
172.16.0.0 255.240.0.0 172.16.0.1 - 172.31.255.254
192.168.0.0 255.255.0.0 192.168.0.1 - 192.168.255.254

Numbers in these ranges are reserved by IANA for private use on TCP/IP
networks and are not used on the Internet
</WINDOWS HELP>

I've always used 192.168.0.* (subnet mask 255.255.255.0).... mainly
because its easy to work out what is an internal address (anything
192.168.0.*) and what is an external address... and also coz most of my
friends/Lan places used it... and it made getting up and fragging easy
:)
