WHOIS Lookup

Lookup domain registration and delegation

If you are querying an Australian domain name it is necessary to complete the CAPTCHA code that appears when you perform a lookup.

The results returning from a WHOIS lookup will vary according to which registry or extension is being queried. Please be aware that some if not all domain registries place limits on the number of queries a given IP address is allowed to make. Limits vary according to domain registry and domain extension queried. In many cases, there are also two sets of WHOIS results. These two sets are known as thin WHOIS and thick WHOIS. The WHOIS results we display at Whois® are normally the same as those you would see if you were to do a PORT 43 WHOIS query from the command line.
