|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.
|Looks up an IP address, showing what domains refer to it (website, mail server, DNS server).|
|Lets you search domains for a string. For example, 'google' will show all domains with 'google' in them.|
See the IP heat map that shows where servers are among the 4B IPv4 IPs.
Drill down IP ranges, seeing how many hosts are in each IP range, who the IPs are delegated to, and the reverse DNS.
