|Searches through our proprietary historical DNS database for DNS data on a domain (checking one date each month, the rest of the data is archived). How big is the full database? Huge. 40+ TB compressed. |
The data accessible here goes back to mid-2008. It covers all .com, .net, .org, .biz, .info, .mobi, and .name domains.
