        Dear Jesse:

        I just dug out my LINUX Network Admin Guide (by Olaf Kirch) (a
very handy book).  I knew that 192.168 was a magic number, but some books
don't mention why.  But the LINUX NAG does.  

It says that "these addresses are only valid within your private
network and are not routed between real Internet sites.  These numbers
are: 

  CLASS       |   Networks
--------------------------
   A          |   10.0.0.0 
   B          |   172.16.0.0 through 172.31.0.0 
   C          |   192.168.0.0 through 192.168.255.0 

Note that the second and third blocks contain 16 and 256 networks,
respectively."

Your client's network using IP address 10.x.x.x is fine, and shouldn't
cause problems.  It is Class A, which allows way more nodes than
necessary, but it should work OK.
