Change IP for alias domain

After restoring backups from different server, I had a domain with dedicated ip for Anon_ftp with an alias domain. Changing IP on the main domain didn't change it for the alias domain.

The only option I had for changing IP on the alias domain was to change it from the old IP (now non existant on this server since changing the parent changed eth0:x) to the shared one. I need to change it to the new ip of the parent so site resolves and anon_ftp works.

After changing it to the shared, I no longer had an option to change it again. Deleting the alias domain and recreating it did the trick.
