Should?  Yes, assuming you're referring to their resolvers.  An
end-user/client network should only need access to a caching resolver. 
It's up to the resolver to contact the TLD Root and/or authoritative
nameservers on your behalf.

Everyone.  There's no other way for all of the resolvers spread
throughout the globe to resolve your information.  If you haven't
already, I'd strongly suggest putting your nameservers in a DMZ.
