Ok - I wanted to share my latest concoction with you all. I just finished building an app/website that will allow you to search the entire .com zone file (had to get approval from Verisign to get access to it). That file contains over 185 million records (duplicates for multi name server domains)... It's such a huge file that I had to build the app so that it is continually looping through and updating two character combination sets (you can see what it's currently updating on the lower left of the app/website). Once it finishes the entire loop (0 through zz), it downloads a new zone file (around 7 gig) and starts the whole process again.
Searching is pretty quick considering the magnitude of the data it's got to crunch through. I suggest you type at least 3 characters or it will take longer than you want.
You can download the results to a spreadsheet as well...
There are some interesting stats in the grid on the right - domain counts/percentages/changes up or down for each 2 character set (in the case of numbers, I just made 1 for each number). Keep in mind that the change values are not yet accurate since it hasn't looped through twice yet... some have been updated...some not yet. The change is interesting in that you'll be able to see what 2 character combinations are being dropped and which ones are being picked up...
You can sort any of the columns too...
If you are in the business of selling domains, it's works great to search on your own domains - I found a whole bunch of other similar domains that I wasn't even aware were registered - and they turned out to be companies with live websites... sooooo...they become potential customers for my domain portfolio. Just one use for the app.
Let me know what you think - Enjoy!
