Reason for my vote of one: Too lazy to use google.

How such validation can help you? It won't guarantee that the domain is valid.
And the domain name wwww.mysite.com can be valid. Isn't it obvious?

Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...

A very quick search using your subject as the search term gave over 1.75 million hits: Google[^]

In future, please try to do at least basic research yourself, and not waste your time or ours.

Bad idea. Domain name like "wwww.mySite.tld" (yes, with 4 'w') can be valid. To make sure it's so, get some Web hosting, obtain some domain name of your own and create a sub-domain "wwww". It will work, I'll guarantee it.

(By "tld" I mean "top-level domain", such as "com", "org", "net", "edu", etc.)

At the same time, "good" URL like "http://www.mySite.tld" can be invalid. So, this validation would be pretty much useless, even though you could easily perform it, without asking such questions.
