In search of the perfect URL validation regex

None of those is a URI, so a URI validator most certainly should not accept them. Just because browsers tend to understand them as a matter of a historical accident does not mean those are valid URIs, just as tag soup that browsers also tend to understand isn't valid HTML either.

Exactly. The goal was to come up with a good regular expression to validate URLs as user input. There’s no way I’d want to allow alternate IP address notations.

Yes... I've found the relevant RFC now. How disappointing! I like 32-bit hex IP addresses.
