What is WHOIS?

The WHOIS service allows users to query a domain name to find the identity and contact details of the registrant. The public WHOIS service is a standard feature of domain name systems around the world.

Afilias Australia operates the public WHOIS service for asn.au, com.au, edu.au, gov.au, id.au, net.au and org.au.

WHOIS provides the following information:

  • registrar of record for the domain name
  • registrant of the domain name
  • registrant contact name and email address
  • technical contact name and email address
  • computers for the domain name.

The service will also respond on port-43 of whois.auda.org.au using the WHOIS protocol  (RFC 3912 https://tools.ietf.org/html/rfc3912 ).


WHOIS does not provide the following information:

  • creation or expiry dates for the domain name
  • registrant telephone, facsimile or postal address
