Frequently Asked Questions
What happened to the previous Hosting History Tool?
The Hosting History Tool is now integrated in the new History Search interface. With the new interface you can search for historical domain data on many different fields like domain name, IP,MX/NS records and Google Tags (Adsense and Analytics). See examples below!
When did you start recording IP/DNS history?
We began recording historical records in 2012, initially saving only A (IPv4) and NS records. In 2014, we expanded our record-keeping to include AAAA (IPv6), MX, and SPF records.
How often do you resolve the IP/DNS records for a domain?
Our DNS crawlers attempt to resolve each domain name every two weeks.
