Find Expired Domains in the DNS Census from 2013

For those of you building PBN's, here's something I came across. In 2013, there was an initiative to perform a census of all the domains in existence. Although they didn't get everything, they amassed a huge collection of domains - over 150 million - all organized by TLD. I've processed a sample of these, and there are definitely some worthwhile expired domains in the bunch. However, since I'm not actively building a PBN, and I'm not a domain reseller, I thought I'd pass along the info.

Heres a link to the torrent for the whole dataset: (it's huge, around 12 GB I think, and if you're on Windows, you'll need 7zip to unpack the compressed files)



Here's a tip if you start processing these - skip the domains at the beginning of the file that start with 0-9. It's almost universally garbage, you'll get better results with domains that start with letters.

This is really a Good Share Buddy.. 14.5GB of DATA.. Start Downloading already..

Thanks for the list but don't you think people have already scanned it through multiple times if the list was created in 2013?

Possibly, but it's not a bad idea overall. You can get zone file access from Verisign for the .com and .net zone files then just download them once per month and look at the previous months (will have to wait the first month) for a fresher list.

I won't say exactly how to do this but if you look for yourself you will find it's not actually that difficult.

People have absolutely scanned through it multiple times. But, since domains get dropped all the time, someone who scanned it last month will get different results from doing it now. Obviously it's not a small task combing through these, and there will be a large amount useless domains (this is true for any method of acquiring expired domains). But due to the sheer volume of domains here, there are still many, many valuable domains to be found.

Thanks for the share. Will look into it when the (slow) torrent is finally finished. I suppose it only includes domains which were (still) registered in 2013, right? It'd be awesome if it includes all domains ever registered, but I don't expect that.

P.S. might want to delete that map with the expired domain scraper .

You're welcome. I'm not sure how the domains were collected, but I'm pretty certain it's not all domains ever -however it could contain domains that were dropped before the data was collected.
