Hmm.  I was momentarily confused.

10.* is class A, which means all 24 bits after the first octet 'matter'
and are controlled by whoever controls your network IP addresses.

Which means that your network is 10.x.x.x, or 10.0.0.0/8, since all
computers on your (non-subnetted) network will have their first octet
equal to 10.

I was originally confused, but then I went and researched and the above
statement should be totally accurate (assuming you read it as I
intended! ;-)

The above explanation is null and void if you have subnetted your
network ;-)

explanation of the /<number> notation)
