Domain names cannot be longer than 255 characters. I assume that includes the top-level sub-domain, like “.com” or “.info”.
Here is a list of long URLs.
- http://tacfit-bodyweight-workouts-fitness-programs.com – 47 characters (Checked on 2013-10-09_00.50.58. Status: Inactive)
- http://hasthelargehadroncolliderdestroyedtheworldyet.com – 48 characters
- http://www.bill-wiese-23-minutes-in-hell-a-biblical-response.com/ – 50 characters
- http://dowebsitesneedtolookexactlythesameineverybrowser.com/ – 49 characters (They say the answer is “No”. If your site does not work in Firefox, fine, just tell me upfront so I don’t waste time figuring it out myself.)
