DNS record types
A, AAAA, CNAME, MX, TXT and NS records: what each does, names, TTL and common setups.
The record types you can create in DNS Management, and what each one is for.
| Type | Points a name at | Example value | Typical use |
|---|---|---|---|
| A | An IPv4 address | 203.0.113.10 |
Your website, app or server |
| AAAA | An IPv6 address | 2001:db8::1 |
The same, over IPv6 |
| CNAME | Another hostname | example.com |
www as an alias of your main domain |
| MX | A mail server, with a priority | mail.example.com (priority 10) |
Receiving email |
| TXT | Free text | v=spf1 … |
Email authentication (SPF, DKIM, DMARC), domain verification |
| NS | A nameserver | ns1.example.com |
Delegating a subdomain to other nameservers |
Names
@means the domain itself (example.com).www,blog,mailand so on create subdomains (www.example.com).
CNAME rules
Don't put a CNAME on @. The domain itself also needs MX and other records, and a CNAME can't share a name with any other record. Use an A record for @, and a CNAME only for subdomains like www.
TTL
TTL (time to live) is how long, in seconds, other resolvers cache a record. It can be 60 to 86400, and the default is 3600 (1 hour). Lower it a day before a planned change so the change spreads faster, then raise it again.
