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:

  1. Think about my target market.
  2. Think up a few keywords.
  3. Try the keywords at http://www.instantdomainsearch.com.
  4. Find most are registered.
  5. Think up other less interesting keywords…
  6. Find one kinda crappy domain name that isn’t registered and register it because I’m frustrated…
  7. Dwell on the fact that I had a crappy domain name…

Search for Domains V2 (New and Improved with NXDom)

  1. Think about my target market.
  2. Think up a few keywords.
  3. Try the keywords at NXDom.
  4. See 300 results for each keyword.
  5. See lots of possibilities for great domains for each keyword.
  6. Register a great domain (making sure to click the NXDom affiliate link so that Johann gets his rev share).
  7. 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:


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.

  1. Thank you for the blog post, I’m glad to hear that you find NXdom useful. Most of the names were added to the NXdom database because they expired, that means the previous owner didn’t renew their registration.
