We should use net.JoinHostPort() here, to account for IPv6 addresses; https://pkg.go.dev/net#JoinHostPort

But I need to have a closer look, as there's many possible formats (ports mapped here can also have the protocol (e.g. 80/tcp), which may have to be taken into account here.
And of course we also have PortMap (which is a list of mapped ports) 😞

Do we know if HostIP defaults to 0.0.0.0 (or :: IPv6)? 🤔
