How does Domain Name Analyzer check domains for availability? Can I use my own whois proxy?
Domain Name Analyzer works by querying whois servers that listen in on port 43. This is the standard way of checking domain names. Domain Name Analyzer will not connect to the web based lookup tools provided by registrars. This is because • This will make the software dependent on the output format of third party services. • Registrars do not approve of software tools that connect to their web resources. If you have your own proxy server that uses port 43, you can configure DNA to use it. If you wish to know more about the whois service, please see our knowledge base articles on whois.
