DNS records you should know 👇
DNS issues are subtle, cached, and often blamed last, but they break things fast when misconfigured.
| Record Name | Record Purpose |
|---|---|
| A record | Use when you want a domain to point to a specific IPv4 address |
| AAAA record | Use when you want a domain to point to an IPv6 address |
| CNAME record | Use when you want one domain to alias another (for example www → root domain) |
| MX record | Use when you want to receive email for a domain |
| TXT record | Use when you need to prove ownership or configure email security (SPF, DKIM, DMARC) |
| NS record | Use when you want to delegate DNS control to specific name servers |
| PTR record | Use when you need reverse DNS, commonly for email deliverability |
| SOA record | Use when defining the authoritative metadata for a DNS zone |
