`GET https://api.deepinfo.com/v1/analyze/dns-history?domain=deepinfo.com&type=MX`

The MX record history of deepinfo.com: the same five Google mail servers since December 2020, each listed twice.

Example 4 of 7 · [DNS History Examples](/reference/lookup/dns-history/examples/) · endpoint: [DNS History](/reference/lookup/dns-history/)

Tags: `param` `domain` · `param` `type` · `value` `deepinfo.com` · `value` `MX`

Asks for the `MX` history of `deepinfo.com` (`type=MX`).

Every value is one of the five Google Workspace mail servers with its priority: `1 aspmx.l.google.com`, `5 alt1.aspmx.l.google.com`, `5 alt2.aspmx.l.google.com`, `10 alt3.aspmx.l.google.com` and `10 alt4.aspmx.l.google.com`. The first five entries hold the long history: first seen on December 26, 2020 and last on September 18, 2026 (the page shows their 10 newest observations). The last five entries list the same servers again, each with two observations, November 26 and December 31, 2021, which fall inside that period.
