`GET https://api.deepinfo.com/v1/lookup/dns?domain=gmail.com&type=MX`

The MX records of gmail.com: its mail servers with their priorities, lowest (preferred) first.

Example 3 of 13 in **Record Types** · [DNS Lookup Examples](/reference/lookup/dns/examples/) · endpoint: [DNS](/reference/lookup/dns/)

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

Asks for the `MX` records of `gmail.com`.

Each value is a priority followed by a mail server: `5 gmail-smtp-in.l.google.com` is tried first, the four `altN` servers (priorities 10 to 40) after it. `values` lists them by priority; `raw` keeps the order the resolver returned them in.
