What is "WWWW" and how we can get it for our web sites

i know what is "www" but, when i was tring to open blogspot and by mistaken i have written 4 times "W" instead of 3 like :

http://wwww.blogspot.com/

and the page opend in front me shocked me.

please tell me what is meaning of "wwww"

and what is technique and logic behind it.

and ho开发者_StackOverflow中文版w we can Launch our website with "wwww".

Thanks

in this case the clever person with the blog wwww has that subdomain at blogspot with the name wwww

'wwww' is a sub-domain - in this case it appears to be the name of the blog on Blogspot.

However, most hosting packages allow you to set up custom sub-domains (like blog.example.com) which can redirect anywhere you want. You could set up a wwww.example.com sub-domain, but there wouldn't be much point unless people regularly misspelled the name of the site (and would potentially be quite confusing too).

Blogspot blogs all have an URL in the form of userorblogname.blogspot.com. wwww.blogspot.com simply takes you to the blog called wwww.
