The data

Everything shown comes from domain registries and public DNS, cached for up to a day. Registries can be wrong, incomplete or out of date, and so can we. Always confirm with a registrar before you buy, sell or make decisions about a domain.

Fair use

Use Simple WHOIS for normal lookups. Don't use it for bulk or automated harvesting of registration data, for sending unsolicited messages to domain holders, or for anything illegal. Registries limit how their data may be used, and those limits apply to you too.

No warranty

The service is provided as is, without guarantees of accuracy or availability. We're not liable for decisions made based on it.
