I have never fully understood the difference but there are URI's and URL's in the lexicon. (That's a letter I in the first one.)
I thought a file: and mailto: were URI designators and URL was for network links but I'd be happy to see a proper definition. I think all URL's are in fact members of the larger set called URI.
And:
The UNIX tool dig is usable for determining if the domain part of a URL is valid.
