Looking for a bit of confirmation, i'm wanting to supernet a class B network which is current setup as class C's. I'm just wanting some confirmation that i'm not barking up the wrong tree. Network config is as follows

172.27.0.0
Subnets
2-80 configured as class c in the b address space

Setting up
172.27.96.0 /19 (255.255.224.0)

Fingers crossed... this shouldn't affect any of the other networks? True or?
