Sub1 in IIS

I have a working site:mysite.com

In the DNS Manager I assigned a Host (A) as sub1 and a IP Address as 192.168.1.xxx close to the IP Address of the Domain.

Then made it a Static IP. 

Then in IIS assigned sub1 as a Site added it to an Application Pool and Binded it to *80 under sub1.mysite.com. 

I also populated it with a working ASP.net Program just like mysite.com. 

But when I entered sub1.mysite.com nothing comes up.
