What is DNS Lookup?
DNS Lookup queries a domain's standard records — A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV — plus rarer types such as RRSIG, NSEC, TLSA, SVCB and HTTPS, from the resolver you choose (Google, Cloudflare, Quad9).
Each record shows its TTL alongside total query time. TTL controls how long resolvers may cache the record; lowering it before a planned change makes the change propagate faster.
"ALL" queries 13 common types in parallel and lists only those that answered. An empty answer and NXDOMAIN are different: the first means "the name exists but has no record of that type", the second means "the name does not exist".
Frequently Asked Questions
10 questionsWhich record types are supported?
A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, PTR, DS and DNSKEY. "ALL" queries every type in parallel and lists only the types that returned records.
Why do different resolvers return different results?
Each resolver keeps its own cache. After a DNS change, some resolvers serve the old value until its TTL expires. Persistent differences may indicate a configuration problem.
What does TTL mean?
TTL (Time To Live) is how many seconds a record may be cached by resolvers. Lower TTLs propagate changes faster at the cost of more queries; 300-3600s is a common balance.
What does NXDOMAIN mean?
NXDOMAIN means the queried name does not exist in DNS at all. An empty answer with NOERROR means the name exists but has no record of that type — a different situation.
I deleted a record but it still shows — why?
Resolver caching. Queries keep returning the old value until the deleted record's TTL expires. Try different resolvers (Google/Cloudflare/Quad9) to see which have refreshed, and use DNS Propagation to track it.
Can a name have both a CNAME and an A record?
No. Per RFC 1034, a name with a CNAME can have no other record type. That's why you can't put a CNAME at the apex — the apex already requires SOA and NS. Providers' ALIAS/ANAME features solve this server-side.
Should I use the dedicated SPF record type?
No. The old SPF type (99) was deprecated by RFC 7208; SPF must be published as TXT. The type exists in this tool only to diagnose legacy setups.
What are HTTPS and SVCB records for?
They advertise a service's connection parameters — supported protocols, alternative ports, ECH keys — over DNS. An HTTPS record lets a browser open its first request straight over HTTP/2 or HTTP/3 to the right endpoint, removing a redirect round-trip.
Is there a limit on the number of records?
No hard protocol limit, but a response that doesn't fit in 512 bytes over UDP falls back to TCP. That's common on domains with many TXT records, and resolution breaks if a strict firewall blocks TCP 53.
Why does query latency differ between resolvers?
If the record is in the resolver's cache the answer arrives in milliseconds; otherwise it must walk from the root servers to the authoritative server. That's why the first query is slow and an immediate repeat is fast.
