Can anyone tell me why ipa-server-install is saying the ::1 address is not assigned

It looks like the test is suppressing the actual error raised. You might get more info from this:
# python
from ipapython import ipautil ipautil.CheckedIPAddress('::1', allow_loopback=True)
A ValueError is being raised but this is caught and not re-raised in ipaplatform/redhat/tasks.py::check_ipv6_stack_enabled()

The problem is on this line in ipautil.CheckedIPAddress with the netmask=ifdata['netmask'] call
ifnet = netaddr.IPNetwork('{addr}/{netmask}'.format( addr=ifaddr, netmask=ifdata['netmask'] ))
On my CentOS 7.3 box which has python-netifaces-0.10.4-3.el7.x86_64 it works
On my CentOS 7.4 box where I am trying to install ipa-server-4.5.0-22.el7.centos.x86_64 and it has python2-netifaces-0.10.5-2.el7_4.x86_64 installed, it fails with:
ValueError: IPAddress() does not support netmasks or subnet prefixes! See documentation for details.
So I don't see how anyone has been able to install ipa-server on a RedHat 7.4 or CentOS 7.4 box
Might be related to this:

Hi,
this is a known issue, see #7021 ipa-server-install failure on checking matching interfaces - invalid format of netmas [1]. The fix was provided in FreeIPA 4.5.3, but I don't think it is available in CentOS.
HTH, Flo
