NXDom rocks…
A couple of months ago, Johann Rocholl announced NXDom. Basically, Johann created an algorithm to build millions of likely-to-be-interesting possible domain names and then queried DNS servers to see if the servers knew of the possible domain names. Any domains that got NX (non-existent domain) responses from DNS servers were entered into the NXDom database as available. Johann added a nice query interface and, voila!, changed how I search for domains.
Search for Domains V1
I don’t have any particular recipe for searching for domains, but I do something like:
- Think about my target market.
- Think up a few keywords.
- Try the keywords at http://www.instantdomainsearch.com.
- Find most are registered.
- Think up other less interesting keywords…
- Find one kinda crappy domain name that isn’t registered and register it because I’m frustrated…
- Dwell on the fact that I had a crappy domain name…
Search for Domains V2 (New and Improved with NXDom)
- Think about my target market.
- Think up a few keywords.
- Try the keywords at NXDom.
- See 300 results for each keyword.
- See lots of possibilities for great domains for each keyword.
- Register a great domain (making sure to click the NXDom affiliate link so that Johann gets his rev share).
- Dwell on my super cool domain.
The best part of NXDom is that it works very well for very popular terms. A friend is in the CFO business, so we searched on domains ending in “CFO” and found numerous interesting domains:

FWIW
I don’t know Johann and I have no affiliation with NXDom. Everyone to whom I show NXDom gets wide-eyed and starts thinking up domain ideas, so I figured that I’d share more broadly. NXDom has certainly changed, and greatly improved, the way I search for domains.
