Unable to add Two different class IPs in a windows cluster.

Hello,

I am trying to configure windows Cluster in server 2012 for SQL server Always availability group.in my network domain controller is running on 10.1.1.0/24.Due to some reason i cannot use class 10.1.1.0/24 IPs for cluster and SQL Listener

I have assigned class A 10.1.1.0/24 range Ip and class  C 192.168.1.0/24 range Ip on single LAN card of my sql servers

Server1 10.1.1.10/24 and 192.168.1.10/24

Server2 10.1.1.11/24 and 192.168.1.11/24

When i try to create cluster its only pick class A 10.1.1.0/24 network not class C network 192.168.1.0/24 network. and If i create cluster with 10.1.1.0/24 then how i can able to addclass C network 192.168.1.0/24 in cluster

Please help me on this issue.Thank you in advance
