How specific can you be when "blocking" ip addresses?

I know that OpenDNS doesn't actually block pages but redirects traffic as such but how specific can I be?

If I want to allow access to say Facebook but not a specific person's page then is this possible or can I only "block" the whole domain?

For example if I wanted to allow access to Facebook.com but prevent access to Facebook.com/Johnsmith (or the ip address equivalent) is that possible?

Can I also prevent that page being accessed via a mobile phone app if I can establish the ip address of that page?

Apologies to any John Smiths out there lol!

OpenDNS can only block by domain, blocking a specific page is not possible at this time. Anything before or after the /'s in a URL is no longer part of the domain. Facebook.com can be blocked by OpenDNS, but facebook.com/johnsmith cannot without blocking all of Facebook because the /johnsmith is no longer part of the domain.

Your router may allow blocking URLs or keywords. Check it out. You can block specific URLs also with browser built-in feature or with browser add-ons.

The OpenDNS Community has moved!
