About dot.bi

A free domain intelligence platform, built on public data, openly licensed datasets and registry zone files used under their access agreements.

What it does

Type any domain name and dot.bi assembles what can be known about it from public sources: registration data, DNS records, the hosting network, the web stack behind the home page, email authentication, age, and the history of changes dot.bi has observed since it first saw the domain. Beyond single lookups, dot.bi lets you discover domains by keyword, length, TLD, dictionary words, hosting provider or technology, and shows trends computed from everything it has observed.

Who it is for

• Domain investors who want quick, honest facts about a name and its neighbours on other TLDs.
• Developers and IT teams who need a complete technical profile of a domain in one page.
• Brand and security teams watching look-alike names and pivoting on shared infrastructure.
• Researchers and journalists who need TLD and hosting statistics with a stated methodology.

What it is not

dot.bi is not a registrar, a marketplace or a backorder service, and it does not list expired, pending-delete or “available” domains. Absence from dot.bi never means a name is free. Registrant contact details are never shown.

How it is built

Every observation is stored with its source and timestamp, so the dataset becomes a history that grows every day. The methodology explains each value, and the sources page lists every dataset and license.

Free, and funded by ads

dot.bi is free to use. To cover hosting it may show advertising; see the privacy policy for what that means for you.
