Blocking Hulu

How do you block Hulu with firewall rules?  I've added DNS Group definitions for 

www.hulu.com and hulu.com.

  It doesn't block the site from loading.  Doing an NSLOOKUP on 

www.hulu.com

 yields:
Non-authoritative answer:
Name:    a1700.g.akamai.net
Addresses:  66.162.246.208
          66.162.246.209
Aliases:  

www.hulu.com

          

www.hulu.com.edgesuite.net

Doing an NSLOOKUP on 

www.hulu.com.edgesuite.net

 yields:
Non-authoritative answer:
Name:    a1700.g.akamai.net
Addresses:  66.162.246.209
          66.162.246.208
Aliases:  

www.hulu.com.edgesuite.net

Now if I block 

www.hulu.com.edgesuite.net

 then Hulu gets blocked, but other sites get blocked to (only one I'm aware of for now) like foxnews.com.

Sorry for putting in the code tags but this editor was changing the name of the URL's to something I did not want.

Thanks in advance!
