f you need to get the whois information for a specific domain, why not using PHP to do it? The following function take a domain name as a parameter, and then display the whois info related to the domain.

  1. function whois_query($domain) {
  2.  
  3. // fix the domain name:
  4. $domain = strtolower(trim($domain));
  5. $domain = preg_replace('/^http:\/\//i', '', $domain);
  6. $domain = preg_replace('/^www\./i', '', $domain);
  7. $domain = explode('/', $domain);
  8. $domain = trim($domain[0]);
  9.  
  10. // split the TLD from domain name
  11. $_domain = explode('.', $domain);
  12. $lst = count($_domain)-1;
  13. $ext = $_domain[$lst];
  14.  
  15. // You find resources and lists
  16. // like these on wikipedia:
  17. //
  18. // http://de.wikipedia.org/wiki/Whois
  19. //
  20. $servers = array(
