dnstimelineDNS History Lookup
Enter a domain to see the mail servers (MX), nameservers (NS), TXT records and aliases (CNAME) recorded for it, each with the date it was first recorded, and the mail and DNS providers recognised from them.
DNS record guides
Dates shown in the timeline
Each dot represents a recorded DNS value. Its date usually comes from the first time it was recorded. The history does not show when that value stopped being used or confirm the date of a provider switch.
Select a record to see its details. The notes below the chart identify recognised providers and link to the records used. To check what is published today, query current DNS, for example with dig @1.1.1.1 example.com MX. More about dates and coverage →
Different hostnames can belong to the same service. Google Workspace supports two MX formats; recreating an Amazon Route 53 zone can assign new nameservers. Check the record values and provider context before interpreting a change.
Records included in a search
A search returns up to 50 observations across MX, NS, TXT and CNAME from Profundis. The most recent observations come first; the chart sorts them by their supplied timestamps. The IP addresses recorded for a domain are on ip-history.net.
Mail and DNS providers are named when an MX or NS hostname matches a pattern listed in the MX and nameserver guides. DMARC and DKIM use other names and are not in the history. When more observations exist, the result counter shows the available total; further filters and exports are on Profundis.
Frequently asked questions
How can I see old DNS records for a domain?
Enter the domain above. The page lists the values recorded for it, each with its date, and plots them on one time axis. Beyond the 50 shown, search the domain on Profundis.
How far back does the history go?
It depends on the domain. The page shows the 50 most recent observations, so a busy domain may only go back a few months while a quiet one can go back years.
Why is there no history for my domain?
The history only contains names Profundis has collected. A new domain, or one that has not yet appeared in the public sources it reads, can have few or no observations.
Can DNS history show who owns a domain?
No. Ownership is recorded in WHOIS and RDAP, not in DNS. A nameserver change often comes with a transfer or a sale, but it does not prove one.
Is it free? Do I need an account?
It is free and needs no account. A Cloudflare Turnstile check runs when you search. Each IP address can run up to 10 searches per minute, 30 per hour and 100 per 24 hours; IPv6 addresses in the same /64 share these limits. Searches that need a new request to Profundis also count toward a daily limit shared by all visitors, which resets at midnight UTC.
