Every record, as it was
A, MX, NS, TXT, CNAME. Each value is stored the day it was seen, so the record you read is the record that was actually live, not a reconstruction.
Historical DNS lookup
Look up the DNS a domain used to have.
Current DNS tells you where a domain points today. It says nothing about who ran it last year. DNSTimeMachine keeps the full archive: pull up any domain's past A, MX, NS, TXT, and CNAME records to audit its history before you trust it, acquire it, or build on it.
For anyone searching historical DNS lookup, past DNS records, old DNS records of a domain, or DNS record history.
How the history reads.
One domain, every record, each value stamped with the day it first appeared. That is the whole product: the past DNS you cannot get from a live lookup.
The exact date it flipped
Every change is stamped with the date it first appeared. Pinpoint when a record moved instead of guessing from a support ticket timeline.
No login to read history
Type a domain, read its past. The lookup is the product, so checking what a domain used to point to takes one field and one click.
When teams reach for this.
- Debugging why mail suddenly bounced
- Confirming when a domain changed hosts
- Auditing a domain before you acquire it
- Reconstructing what a vendor's DNS looked like last quarter
"What did this point to before?"
The question current lookups cannot answer. Enter a domain above and we will keep its history for you.
