3. Zone Details: .ntt

The .ntt domain is a branded top-level domain designated for use by Nippon Telegraph and Telephone (NTT) Group and its subsidiaries. It establishes an explicit, company-controlled namespace for official web properties, service offerings, and digital identities linked to the NTT organization, separating corporate assets from the general public domain space.

Typical use cases for .ntt include corporate websites, product and service pages, customer and partner portals, cloud and network management interfaces, developer resources, and documentation. As a brand TLD, it communicates an official NTT presence and helps users quickly identify resources that are maintained or endorsed by the organization, supporting brand recognition and operational clarity.

NTT elects to use a branded TLD to centralize domain governance, protect intellectual property, and streamline security and policy enforcement across global business units. Registrations and second-level names under .ntt are generally controlled by the company to ensure consistency, reduce namespace conflicts, and maintain trust in externally facing and internal services.

Coverage and methodology for .NTT data

The downloadable file contains domain names from available sources, one per line in gzip-compressed plain text. It is a domain list, not a raw DNS zone file containing resource records, a WHOIS export, or a verified list of active websites.

Complete zone-file coverage. The .NTT domain list covers every domain name present in the complete zone-file snapshot. Registered domains absent from the zone file are not included, and presence in the zone does not confirm a working website.

Additions and removals describe observed changes between dataset observations, not confirmed registrations or expirations; source changes and gaps can also affect counts. The coverage label describes the current dataset and does not establish comparable coverage across historical snapshots. Verify registration status separately before outreach, security decisions, or domain purchases.

The daily update target is 9 AM UTC. Use each file's snapshot date when scheduling imports or comparing archives; delivery can be affected by source delays. Historical availability varies by zone and date.

For reproducible analysis, record the zone, snapshot date, downloaded filename, and filtering rules. Usage is subject to our dataset license; enterprise and redistribution licensing is available separately.

.NTT domain list questions

How many .NTT domains are in the zone?

The .NTT zone contains 13 domain names in the complete zone-file snapshot dated 02 Oct 2026. Registered domains absent from the zone file are excluded.

Is this a complete .NTT domain list?

The .NTT domain list covers every domain name present in the complete zone-file snapshot. Registered domains absent from the zone file are not included, and presence in the zone does not confirm a working website.

How do I download the .NTT domain list?

Sign in with an account that has download access and use Download Domain List above, or automate the download with the API examples. Check plans and download limits before subscribing.

What format is the download?

A gzip-compressed plain-text file with one domain name per line. It contains domain names rather than DNS resource records, registration contact details, or website content.

Can I download historical .NTT lists?

Available dates appear in the historical domain list table. Archive coverage varies, and downloads require historical access. See historical datasets for details.

Are removed domains expired or available to register?

Removal from an observed list does not establish expiration or availability. Check current registry or registrar information before attempting to register a name. The same limitation applies to expired / removed domain datasets.

When is the dataset updated?

All datasets have a daily update target of 9 AM UTC. Check the displayed snapshot date because source availability and delivery delays can affect individual files.
