I know that in Open DNS I can block the whole country domain suffixes i.e. .uk .cz .ca etc. Is there a way to do the same with Norton DNS? Mainly because I never receive any e-mail from .cz nor I have the understanding of a language that most of the foreign websites employ so no interest in visiting them (yeah I know ignorant American). By blocking those domains I reduce the drive by attack surface so there is a logic behind that. I know that Online Armor can block countries but I would rather employ a whole house solution (DNS IP in a ROUTER) then a per pc basis since not every pc in my houses uses the same protection.
