Ricerca DNS
Tutti i tipi di record, con TTL e stato DNSSEC, interrogati in tempo reale dal nostro client DNS.
Guide ai record DNS
- AWhat is an A record?Maps a name to an IPv4 address.
- AAAAWhat is an AAAA record?Maps a name to an IPv6 address.
- CNAMEWhat is a CNAME record?Makes a name an alias of another name.
- MXWhat is an MX record?Names the mail servers that accept email for the domain.
- TXTWhat is a TXT record?Free-form text, mostly email policy and domain verification.
- NSWhat is an NS record?Delegates the domain to its authoritative name servers.
- SOAWhat is an SOA record?Zone metadata: primary server, contact, serial and timers.

DNS turns names into the records machines need: addresses (A, AAAA), mail servers (MX), aliases (CNAME), text policies (TXT), delegation (NS, SOA) and certificate rules (CAA).
Queries are sent live by our own DNS client to a validating recursive resolver, so you see what the internet sees right now. Each record shows its TTL — how long resolvers may cache it — which is why a change you just made can take a while to appear everywhere. The DNSSEC badge reflects the resolver’s validation (the AD flag).

Why do I see different results than my computer?
Your device uses its own resolver, which may have cached an older answer until the TTL expires. Some providers also return different answers depending on the client's location.
How long does DNS propagation take?
There is no propagation as such — resolvers refresh when the cached record's TTL runs out. Lowering the TTL before a change shortens the wait.
What does NXDOMAIN mean?
The name does not exist in DNS. NOERROR with no records means the name exists but has no record of the requested type.
