Top-Level Domain Zone File Information

Top-Level Domain (TLD) zone files are files maintained by Verisign that map active second-level domain names with the Internet Protocol (IP) addresses of the name server for the domain name.

Request Access

A separate file is maintained for each of the .com and .net TLDs. The TLD Zone Files do not contain domain names in the following states: server hold, client hold, pendingdelete, and redemptionperiod. In addition, the TLD Zone Files do not contain any domain names that do not have name servers associated with them.

Domain Name Base

The domain name base is the active zone plus the number of domain names that are registered but not configured for use in the respective Top-Level Domain zone file plus the number of domain names that are in a client or server hold status.

The domain name base and the active zone change frequently and are updated on this page at least once per day. The update times may vary each day. Today’s domain name base is not necessarily indicative of results that may be expected for the current financial quarter or year.

The daily domain name base provided on this page may not be comparable to domain name counts we disclose elsewhere. The domain name base may also reflect compensated or uncompensated judicial or administrative actions to add to or remove from the active zone an immaterial number of domain names.


The Centralized Zone Data Service

Access to the zone files for the .com, .net and .name TLD and all other Verisign-operated generic TLDs is available through ICANN’s Centralized Zone Data Service (CZDS).

If you are interested in applying for access to the zone file(s) for the .com, .net and .name TLD and/or other Verisign-operated generic TLDs, please visit the CZDS portal at and follow the instructions located there to submit a request for access.
