That's fine, but "suspicious" is quite subjective and I need your help = to define it better if I'm to write a simulator of your suspicion. Here is a new attempt, simplified a bit: (rx-let ((octet (** 1 3 (in "0-9"))) (ipv4 (: octet (=3D 3 "." octet))) (hextet (** 1 4 (in "0-9a-f"))) (ipv6 (: (? "::") hextet (* (or ":" "::") hextet) (? ":" (or ":" ipv4))))) (string-match-p (rx bos (or ipv4 ipv6 (: "[" ipv6 "]")) eos) domain))) We could simplify it further and relax the requirement on octets and = hextets (which seems to be what they are called, rather incongruously) = but then it wouldn't catch what you previously thought were suspicious.
