Understanding DNS records (A, AAAA, CNAME, MX, TXT)
Updated on 08/10/2026
- A: links a name to an IPv4 address (e.g.
@→203.0.113.10). - AAAA: the same for IPv6.
- CNAME: creates an alias to another name (e.g.
www→example.cm). - MX: designates the server that receives your email, with a priority (lower = preferred).
- TXT: free text, used for verification (Google, Microsoft) and email security (SPF, DKIM, DMARC).
- SRV: locates a service (VoIP, Teams, etc.).
@ stands for the domain itself. The TTL is the caching time (in seconds).
