When attempting to use kuard where
/etc/resolv.confcontained an IPv6 for the nameserver, it would error when making the DNS query due to net.Dial expecting the IP to be surround with square brackets. In order to detect if it's IPv6, it parses the IP string to anet.IPand relies on To4() returning nil for determining it's not a v4 and so must be a v6.
