[Freeipa-users] 32 bit netmask detection and error during install

[Jeff Clay]

I’m trying to install FreeIPA on CentOS 7. The server I’m using is a Google Cloud Compute Engine instance. For some reason, they assign all instances a /32 bit netmask on the internal interface even though you have your own private /20 subnet. 
When installing freeipa on these vm's, you get the error "Error: Invalid IP Address 10.128.0.5: cannot use IP network address 10.128.0.5”

Here are the settings for the interface.
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1460
        inet 10.128.0.5  netmask 255.255.255.255  broadcast 10.128.0.5
        ether 42:01:0a:80:00:05  txqueuelen 1000  (Ethernet)
        RX packets 17904  bytes 116212393 (110.8 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 19001  bytes 3287390 (3.1 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

How can I bypass that error and should /32 mask detection really be there?

Thanks,
