Top-level domains list

A top-level domains list contains country-code top-level domains (ccTLD) and generic top-level domains (gTLD). The top-level domain is the part of the fully qualified domain name (FQDN) that follows the last dot. For example, in www.mydomain.org, org is the top-level domain. This feature allows administrators to apply a policy action to requested domains based on the top-level domain. Note that you cannot create a top-level domains list with the com, org, and net top-level domains.

Important: When creating a top-level domains list, make sure that you consider the policy action associated with the list and the impact it may have to your enterprise. Depending on the top-level domain and the policy action, an enterprise may block a large amount of traffic.

Each entry in a top-level domains list is counted and deducted from the 200,000 entries that are allowed for all custom list entries.

Like other configuration changes, you must deploy a new or updated list to the ETP network. Top-level domain lists deploy in the same 20-30 seconds as other configuration changes.
