What site lists all active domains with a keyword?

[DubDubDubDot]

What is that site where you can enter in a keyword and it will report all known active domains to contain that keyword? I believe it uses the DomainTools API to do this.

DomainTools has this ... in the homepage click on 'More Tools and Services' and there click on Domain Search (second in the left column)




or from any page that has the big blue bar on top click on 'Domain Search' on the top left
