What is a WHOIS?

A whois (pronounced who is) is a common protocol that allows looking up registration information on a domain name or IP address.

There are many databases available to make these kinds of lookups nowadays, so you can use many websites that will provide you with the same information on the queried domain. The information gathered by these databases is quite complete, but not everything can be made public.

  • Registrar: The commercial organization that manages the reservation of internet domain names.
  • Registrant: The person or entity that registered the domain name. Also referred to as the domain owner.
