I was just talking to a friend of mine last night on how to do bulk lookups for our domain http://www.droppertunity.com. We really didn't have much of an idea on where to start, but thanks to your scripts I have a great understanding of where to go now. Awesome! Thank you! :) WOW! You must be psychic!

What you do is copy the script into a text editor, save it as bulk_availability.php, and then upload it to your server. Then you go to www.yoursite.com/path/to/bulk_availability.php in a web browser, replacing yoursite.com with your domain name, and path/to/ with the path you uploaded the script to. It will display a text area for you to paste the list. Then you just click submit and wait. 100,000 domains will take a while to scan though, and if your server isn't configured correctly you may run into issues with the script timing out. Let me know if you have any problems. @ Cathy

In the script bulk_availability.php were do I place my list? I have about 100,000 I would like to check for availability. Thanks! Hi

Whois-Servers.net gets their data directly from the registries, and that is what the script I provided uses to do the availability checks. We have a C# .net version of the program that is multi-threaded and can scan upwards of 25,000 domains a minute, but we're not really keen on giving that out. Zone files are a good method if you're only scanning gTLDs, but ccTLD zone files are difficult to get your hands on. Plus, the last time I downloaded the .com zone file it was around 1.5 GB, so if you have a lot of zone files to download it can require a massive amount of bandwidth to keep them up to date.

Just to add to this: Registrars do (read "should") not use the whois to determine availability of domain names, as most registries do provide an alternative realtime availability lookup via their APIs. A lot of domain suggestion tools also us a combination of lookups and zonefiles in order to determine availability of a large number of domain variations in a short time.
