Everything DNS knows about a name.
Look up A, AAAA, MX, TXT, NS, CNAME, SOA and CAA for a name in one query, answered by a resolver that validates DNSSEC.
Enter a name.
We ask our resolver for every common record type at once.
You get all of them on one page, with their TTLs.
What each record is for
One query per type, all at once, answered by our own resolver. An empty set means the name has no records of that type — not that the lookup failed, which is shown separately. If the name is an alias, the CNAME is shown first: otherwise every other set is empty and nothing says why.
A and AAAA are where the name points, in IPv4 and IPv6. A name with only an A record is invisible to an IPv6-only client.
MX is where mail for the domain goes, lowest preference number first. No MX means mail is delivered to the A record instead, which is almost never what anyone intended.
TXT holds SPF and domain verification strings. NS is which nameservers are authoritative — if these disagree with your registrar, that is the fault.
SOA carries the serial and the negative-cache time: the last field is how long the rest of the internet remembers that a name here does not exist. CAA says which certificate authorities may issue for the domain; an empty set means any of them.
