When a domain or IP address is not found in a WHOIS search there are severalĀ 

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; orĀ 

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