Blocking specific website for particular range of ips

Hi Everyone,

Really, Is someone has a idea to block a website www.youtube.com for particular range of ips in the network. Now I can able to block this website for the entire network. This is not enough for my office.
Some of them want to look. So I can block only for specific range example the 192.168.0.161-180.
Others can watch.

Last one week seriously surfing the web and didn’t find any solution.

Please help me who done already.

Thanks
Jose

Are you still referring to this scenario: http://forum.mikrotik.com/t/how-to-block-specific-port-for-range-of-ip-addresses/40122/1

If so, did you implement the address lists as suggested in that thread? Can you post your configuration of what you did to make the proxy work here?
