Whois Server Configuration

Domain Name Analyzer Professional supports a large number of top level and country code domains. It also supports any domain extension that allows lookup through a port 43 whois server. So if your country code is not supported, you can easily add support for it.

For more details please see the knowledge base article on whois server configuration.

Minimizing whois lookups by using DNS checks

The software may be configured to avoid whois lookups for domains that have an associated website. This will help ensure that your IP is not banned by registrars for too many whois lookups.

To do this, use the

Lookup > Do Minimum Whois Lookups menu option.

Once the above option is checked, the software will first check if the domain name resolves to an IP address. If it does it will assume that the domain is registered. Otherwise it will do a basic whois lookup to confirm the availability.

The above method will not work for all country codes, but does work for the common TLDs like COM, Net, Org, etc.
