Show both ipv4 and ipv6 address for the hosts

[Gagi2k]

First of all, big thx for the nice server. I'm currently trying it out on my VPS and found a few things which would be cool to get fixed.

If you add a host and update it with a ipv4 and a ipv6 address, both addresses are available on the DNS, but the hosts view only shows the last updated entry. It would be nice if it could show both entries.

Good point, will see if I have the time to implement this feature
