A) On a different machine entirely, dedicated to DNS lookups B) Using a tool that caches DNS results, so it doesn't lookup the same IP address 1,000 times DNS lookups usually (by default) take 30 seconds to time-out. You really don't want every page on your site to take 30 seconds to find out that some dial-up user has no domain name for their IP address because there simply is no domain name for that IP. -- Like Music? http://l-i-e.com/artists.htm
