Resellers, whose current systems rely on the WHOIS search for domain availability checks, can implement the following method to avoid the likelihood of blacklisting. The format of the request is a text string of the domain name followed by a `\r\n’ as per a standard WHOIS request. The service will then respond with either the string ‘Available’ or ‘Not Available’ depending upon the availability of the domain name.

For Example
To check the availability of ausregistry.net.au follow these steps:

  1. Connect to:
    – Address: whois-check.ausregistry.net.au
    – Port: 43
  2. Send the string ‘ausregistry.net.au\r\n’ to the server
  3. The server will respond with ‘Not Available’ and then close the connection.
    The above procedure is compatible with standard WHOIS protocol; hence any reseller interface that is built to use WHOIS will be able to use this system as well.

Alternatively, the standard *nix whois command can be used as follows:

whois -h
