How is this possible ??? Can someone please explain

I just found this domain.

http://www-nursing-careers.com/

It's fully working, how is that even possible? Please notice the "-" after the www instead of "."

You can go to that Url, can someone explain what I don't know ?

 

Hmm I had no idea that was possible, prob something new or something really old.

 

lol you cant understand it's
hxxp://www.www-nursing-careers.com

 

it's an old trick, like registering www.wwwmyspace.com, etc. Kind of worthless since I doubt there's much type in traffic.

 

Yeah thats right the www. on a domain is just a subdomain of its name, another example is mail. domain. Same goes for the name being a subdomain of .com.

You can register the domain but people will think its strange going to www-

 

hehe what was I thinking....Just thought I stumbled over a black hat secret that no one knew about lol

 

Haha.. I just wondering what the topics it is.. It just a trick.

It will look weird with www..

 

I wonder why they registered it like that... pretty lame trick
