What you currently have is fine. You say "seems to work mostly OK", does this imply that it is it not working 100% how you would have expected. Heres a bit more of an explanation for interest sake. The following description assumes classful networking ipv4 addresses are made up of 4 octets x.x.x.x You have not mentioned a subnet mask but I suspect on the router you have entered or it has defaulted to 255.255.255.0. The address range you are using is known as class A private address range which implies a subnet mask of 255.0.0.0 As such the network you are using (if i have guessed correctly) is actually a subnet of the 10.x.x.x network, i.e 10.0.0.x. (due to the subnet mask of 255.255.255.0) As it is a subnet it implies that you are already employing sub-netting. If however, you were using a subnet mask of 255.0.0.0 then you could say that you were NOT subnetting the 10.x.x.x network. You are free to use whatever private addresses you choose and subnet as little or as much as you like. You could also use public addresses but that would be frowned upon and some equipment may not accept public address ranges on the LAN side. It will also cause issues if you were to one day connect your (sub)network to the internet.
