I always thought that navigating to www.jsbin.com is like jsbin.com

Now - after i try in my browser :

http://jsbin.com/ is working

but http://www.jsbin.com/ is not working.

is there a reason for this ?

  • There is no DNS entry for www.jsbin.com? try nslookup www.jsbin.com and then nslookup jsbin.com, compare the results (or use dig if you're not on windows) – rene Nov 25 '12 at 14:07

The use of www as a subdomain to host the primary website for a domain (with duplicate content or redirects on the domain itself) is a convention, not an automated feature of DNS.

For www.example.com and example.com to return the same website requires that the controller of example.com makes it so.
