The history of www.deepinfo.com, a host name: A, AAAA and HINFO records, with subdomain "www".

Example 6 of 7 · [DNS History Examples](/reference/lookup/dns-history/examples/) · endpoint: [DNS History](/reference/lookup/dns-history/)

Tags: `param` `domain` · `value` `www.deepinfo.com`

Asks for the history of `www.deepinfo.com` without `type`.

A host name has its own history: `fqdn` is `www.deepinfo.com`, `dn` its registered domain `deepinfo.com` and `subdomain` is `www`. It has `a` and `aaaa` records (the same three Cloudflare addresses of each family as the domain itself, last seen on September 3, 2026) and the 2023 `hinfo` value.

## Request
