- MX: the servers that receive the domain mail. The number is the priority; the lowest is tried first.
- NS: the name servers, which have the final say over the domain DNS.
- TXT: free text. Mostly used for SPF, DKIM and DMARC, and to verify ownership with third parties.
- TTL: how many seconds the record may be cached before asking again.
