Support ipv6 better

[sckott]

If e.g, a user requests ipv6 we still are internally looking for the ipv4 IP address, and return that to the user. Maybe just watch if user requests ipv6, then return that IP when it's TRUE

[sckott]

no idea about best practice with ipv6, should we use the v6 address for sshing- or just stick with the v4 address even when v6 enabled

looks like sshing with v6 need to put the ip in brackets like ssh@[<v6 ip address>]
