Blocking TLD’s

A common feature request is to block Top Level Domains in the place of domains. This is extremely effective if an organization knows what TLD's they prefer not accessed on their network.

What is a TLD?

In the DNS hierarchy, a top-level domain (TLD) represents the first stop after the root zone. In simpler terms, a TLD is everything that follows the final dot of a domain name.


For example, in the domain name ‘’, ‘.com’ is the TLD. Some other popular TLDs include ‘.org’, ‘.net’, and ‘.edu’.

How to block a TLD

CleanBrowsing customers have a module in their dashboard that allows them to block TLD's.


Access via Custom Domains > Custom Blocked TLD



With this feature you can block all domains associated with a specific country, for example if you wanted to block all Russian domains you would block the .ru TLD as shown above.
