Actually there is a convention for what subnet SHOULD be used based on the first number in an IP address:
http://en.wikipedia.org/wiki/IPv4_subnetting_reference
A network that starts with 10 has a leading 0 when converted to 8-bit binary, and thus should be a 255.0.0.0 subnet. You'll see that's what the subnet field defaults to when you type in a 10.xx.yy.zz IP.
Conversely, one that starts with 192 leads with 110 when converted to 8-bit binary, and thus should be a 255.255.255.0 subnet.
We're breaking this convention if we use anything other than a 255.0.0.0 actually, but it's just a convention and not really a rule. There are some good reasons to break convention in our case, like preventing teams from interfering with each other.
