What does it mean when a WHOIS lookup returns no information?

Understand the reasons why an IP address may not be found in a WHOIS search.

When a domain or IP address is not found in a WHOIS search there are several  potential reasons:

  • The domain name is not currently registered by an accredited ICANN registrar (most common);

  • The domain name has entered the 'Redemption/Delete' period;

  • The WHOIS server for that domain is not providing data to us; or 

  • The TLD (top-level domain) is not supported by Email Hippo.
