What were you trying to do that didn't work?

When systemd-resolved is used as the resolver, executing getent hosts $(hostname -s) returns the following:

::1       <hostname>

This happens when IPv6 is disabled (using ipv6.disable=1).
The customer (and myself) are expecting the the local IP to be returned instead, e.g.:

192.168.122.254  vm-rhel8

Please provide the package NVR for which bug is seen:

systemd-239-78.el8.x86_64

How reproducible:

Always

Steps to reproduce

1. Boot the system with ipv6.disable=1
2. Start systemd-resolved service with following configuration

   [Resolve]
   DNS=192.168.122.1
   Domains=libvirt
   DNSSEC=false
   LLMNR=no

3. Make sure /etc/resolv.conf uses it

   search libvirt
   nameserver 127.0.0.53

4. Execute getent hosts $(hostname -s)

Expected results

192.168.122.254 vm-rhel8

Actual results

::1 vm-rhel8

Additional notes

Using FQDN returns the appropriate value:

# getent hosts $(hostname -f)
192.168.122.254 vm-rhel8.libvirt
