DNS lookup
Every record a domain publishes, in one query, resolved over DNS-over-HTTPS. Each record carries the TTL that decides how long the old answer stays cached — which is usually the real reason a change has not taken effect yet.
What each record type answers
- A
- The IPv4 address the name points to.
- AAAA
- The IPv6 address the name points to.
- CNAME
- The name this name is an alias for.
- MX
- Where mail for this domain is delivered.
- NS
- The nameservers authoritative for the domain.
- TXT
- Free-text records: SPF, DMARC, domain verification.
- SOA
- The zone’s start of authority, and its refresh timers.
- CAA
- Which authorities may issue certificates for this name.
