i think there is an issue with my patch; i'm following the original idea to have stage ip similar to prod ip

for example: noc01.stg.phx2.fedoraproject.org -> 10.5.126.2
noc01-a.stg.phx2.fedoraproject.org -> 10.5.128.41 [ matches noc01 on 10.5.126.41]

btw with dhcp IPs going from 10.5.128.10 to 10.5.128.20 there will be duplicates

@smooge is it ok to use your stg.phx2.fedoraproject.org file but with the 128 ip space instead of 126?

so we have ips moved from 10.5.126 -> 10.5.128 numbers, but not 1:1

it seems all IPs there are unique, except for fas-all  and 
fas01  both with 10.5.126.86
