Suppport ipv6 checks

I would like to check a self hosted server, that only has a public ipv6 address.

Currently manually entering the resolved ipv6 address gives me an error:

RequestError: Error: connect EAFNOSUPPORT 
ipv6Adress:443 - Local (undefined:undefined)

It would be nice if ipv6 would have some kind of support.

I imagine that just automatically supporting it / falling back to it might lead to confusion, so ideally checks would be made to both ipv4 and ipv6 separately and there is some setting to enable / disable ipv6 to avoid confusion.
