About
The database of domains was initially loaded from the following sources:
- dmoz from Open Directory RDF Dump (~3 million unique domains)
- en.wikipedia.org from Wikimedia Downloads (~800k unique domains)
- Internet Domain Survey from the archive directory (1.3 million unique domains, as of 1997)
- Alexa from Alexa Top Sites (just the first 500 which is free!)
- An old (2003) copy of the entire list of registered domains in .com, .net, and .org (32 million domains)
