Active Directory Forest Trust

Dear Experts,

Thanks in advance ..

I need a your help regarding this.

We have a domain called abc.com and another domain called xyz.com. we want to create a forest trust between these two separate domains. The network setting of of abc.com is mention below.  My question is what would be the network setting for xyz.com. It would be the same like abc.com. If we assign different network configuration like 192.168.x.x can we create forest trust between these domains.
10.10.51.x
255.255.192.0
10.10.51.254
