Common questions
- What is a DNS record?
- A published entry mapping a domain to an address, a mail server, or a text value. Anyone can read them.
- Why has my change not shown up yet?
- Resolvers cache records for the length of the TTL. Until it expires you may still get the old value.
- What is the difference between A and CNAME?
- An A record points at an IP address. A CNAME points at another name, which is then resolved in turn.
- What lives in a TXT record?
- Ownership proofs, SPF sender policy, and DMARC. Several unrelated systems share this one record type.
- Can I see private DNS records here?
- No. This returns only what a domain publishes publicly. Internal records are not visible.
