.docomo Domain

The .docomo domain extension serves the mobile communications business of NTT DOCOMO, Inc., including related telecommunications, information, and content services. A brand extension matters here because customers need to know that a message or site really comes from their carrier, not from someone imitating it.

Domains under this extension are used for corporate and product websites, customer-facing services, and secure communications and email. Customers, employees, partners, and affiliates can use these addresses to reach NTT DOCOMO's official online services. The extension is closed, so registration is limited to NTT DOCOMO and affiliates, and any third-party use happens only by contract. For NTT DOCOMO, one controlled namespace makes real addresses easy to recognize and cuts down on phishing, spoofing, and misuse of the name.
