Say you have User with IPs: 126.96.36.199 188.8.131.52 The domain only has the additional IP: 184.108.40.206 When removing 220.127.116.11 from the User (with dns removed too), DA would remove it from the zone and if it ended up with zero IPs, it would re-add the default IP again. This check was fine for apache, but as the only remaining records were removed prior to the new IP being added, there was no record data to duplicate, so the default 18.104.22.168 didn't add any A records, etc. Fix: change order of check to add any needed IP prior to removing the last IPs from the domain. This will ensure A/AAAA values (etc.) are duplicated prior to removing the only remaining IP, thus not an empty zone.
