So... Has anyone already found the perfect URL validation regex?

/_^(?:(?:https?|ftp)://)(?:\S+(?::\S*)?@)?(?:(?!10(?:\.\d{1,3}){3})(?!127(?:\.\d{1,3}){3})(?!169\.254(?:\.\d{1,3}){2})(?!192\.168(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\x{00a1}-\x{ffff}0-9]+-?)*[a-z\x{00a1}-\x{ffff}0-9]+)(?:\.(?:[a-z\x{00a1}-\x{ffff}0-9]+-?)*[a-z\x{00a1}-\x{ffff}0-9]+)*(?:\.(?:[a-z\x{00a1}-\x{ffff}]{2,})))(?::\d{2,5})?(?:/[^\s]*)?$_iuS/

The dude who came with this solution must be in an hospital somewhere.

@Drillan767
Why https|ftp,

So we have ftp but no http?

Sftp?

@Drillan767 where did u find it?

@D--M https?|ftp matches http, https and ftp

@D--M sftp is like ftp but via ssh. Like a scp but FileZilla can handle it and connect through the 22 port.

@fastidio I googled the last 3 words in your question, and clicked the 3rd or 4th link, that almost has the same question word to word :D

@fastidio @Drillan767

Ignore me, i am retarded.

Rofl, not sure if thats a bad thing

@Drillan767 I've searched this many times, but all answers have errores.

This is the best approach:

@fastidio Fun fact : the long ass answer I gave you is a copy/paste of the last regex given (502 chars) :D

@Drillan767 haha, look at @scoottgonzales's answer, 1347 characters 😵 I think it's the best solution.

@fastidio I should have pasted this instead :'D

@Drillan767 And here I am, getting spooped by telephonenumber regexing.
