At discussion here are the root DNS servers, which are at a higher level in the hierarchy than any of the ccTLD or gTLD domains. We're talking about the (.) level.

e.g. www.google.com.

That trailing dot is never used in a web browser, but it most certainly does exist.

ccTLDs are a great idea, but somewhere around 60% of the top million websites in the world are run off of .com domains; there's no guarantee that a country could block an entire gTLD or ccTLD and successfully limit all questionable content.



If you can refer to outside "roots" by appending some kind of suffix, it's not really a root.
