How to block list of domains like .domain.com, .domain.co.uk under IIS7.5

I want to block all request from list of doamins (let say around 4000 domain) to access my asp.net website hosted on IIS 7.5 web server.

I Have already tried IP Address and Domain Restrictions feature with no luck. When i "Edit Feature Settings" from  right panel and Enable Domain Name restrictions and select Deny from list. This will block all website.

Note that i do not want to use IP restriction because IP address might be change dynamically for a specific domain.

Thanks & Regards,
