IPv6 addresses are getting resolved via socket.gethostbyname(host) causing a failure.

The regex also returns an empty value (if it would work).

A workaround for this is to disable the gethostbyname for now and the regex, and just return the host as is. Using the gethostbyname like this is also ill-advised as it returns an IPv4 address, not both.

My suggestion would be to completely disable host resolutions and pass everything to UFW as is.
