I need whois servers for my new unique software . I need them to check com,org,net,us, biz and other. The more whois servers the better. the software is written on c++ (not the slow .net language) and will be faster that others existing domain check softwares/tools..Will support s4,s5 high anon and transparent proxies.with more such servers and proxies the progrаm can check all (for example, all four-letter domain) for no longer than 1 hour. more that 100 threads. Any help to find valid good whois servers is appreciated
If you download the trial version of WHMCS, it has a file that lists all the TLDs and their corresponding whois servers.
