Does anyone know of a website/database that allows you to find all the registered domain names that contain a particular string?
For example, you could plug in "dreamhost" and see every registered domain name out there that contains it (including "dreamhostel.org" and "dreamhostsucks.com").
I used to use a great site called http://www.domainsurfer.com, which I think is operated by Tucows. I don't think it's been updated for about a year, which makes it pretty out of date.
It was a fantastic short-cut compared to going to a domain registrar and typing every single permutation you were considering.
