Hi,
I have a program that does the same as whois.sc, you can import a list of names (50.000) and the program is checking .com, .net, .org, .info, .biz ans .us. Also the program displays domains onhold, pending delete etc.
The program runs under windows, i also have many other domain tools
1) country lookup PHP, import a list of names and check on the country where specific domains are registered, i use this to check nice names who were registered in my own country so i can call the owner in my own language.
2) mail checker PHP , import a list of domains and checkit on a specific email adress, the result is an list of domainnames registered with an specific mail adress.
if you are interested please drop me a line and i provide you with screenshots and price.
Regards
Michael
