What is a DNS checker?

A DNS checker queries the Domain Name System for every record type of a domain — the addresses it points to (A, AAAA), its mail servers (MX), name servers (NS), verification strings (TXT) and security policies (CAA) — and reports exactly what is published.

Why can't I see a CNAME record for my domain's root?

DNS does not allow a CNAME on the zone apex (example.com itself) — the root must use A/AAAA records. CNAME records only appear on subdomains like www.example.com.

How long do DNS changes take to show up?

Each record carries a TTL (time to live) that tells resolvers how long to cache it — from seconds to days. After editing a record, public resolvers keep serving the old answer until its TTL expires, so propagation can take as long as the previous TTL.

Apa tegese saben jinis rekaman DNS

Sistem Jeneng Domain nyimpen luwih akeh tinimbang alamat domain. Pemeriksa iki takon DNS langsung liwat DNS-over-HTTPS sing dienkripsi lan nglaporake saben jinis rekaman sing diterbitake domain kasebut:

A / AAAA - IPv4 / IPv6 alamat domain TCTerms kanggo. Tanpa paling ora siji, domain ora bisa dadi tuan rumah situs web.
CNAME - alias nuding siji jeneng ing liyane. Ora diijini ing puncak zona, supaya example.com biasane ora bakal nuduhake.
MX — server mail sing nampa email kanggo domain, saben karo prioritas. Ora ana MX biasane tegese ora ana email.
NS - server jeneng kuoso sing njawab zona kasebut.
TXT - teks wangun gratis: kabijakan anti-spoofing SPF, tandha DKIM (ing subdomain), token verifikasi kepemilikan domain.
CAA - panguwasa sertifikat sing diijini ngetokake sertifikat TLS kanggo domain kasebut.
SOA - metadata administratif zona: nameserver utami, kontak lan wektu caching.

Napa mriksa cathetan DNS?

Sawise migrasi utawa suntingan DNS - konfirmasi cathetan anyar urip ing solvers umum, ora mung ing cache komputer dhewe.
Pangiriman email - verifikasi entri SPF / MX bener sadurunge pesen wiwit mumbul.
Tinjauan keamanan - goleki owah-owahan TXT/NS sing ora dikarepke, lan priksa manawa CAA mung dhaptar CA sing sampeyan gunakake.

Tip: Suntingan DNS ora langsung katon ing endi wae - saben TTL rekaman ngandhani solvers suwene kanggo nyimpen jawaban lawas. Kurangake TTL sadurunge owah-owahan sing direncanakake, banjur mundhakake maneh sawise.

FAQ

Pitakonan mriksa DNS

Apa iku DNS checker?

Pemeriksa DNS takon Sistem Jeneng Domain kanggo saben jinis rekaman domain - alamat sing dituju (A, AAAA), server mail (MX), server jeneng (NS), string verifikasi (TXT) lan kabijakan keamanan (CAA) - lan laporan persis apa sing diterbitake.

Napa aku ora bisa ndeleng rekaman CNAME kanggo root domainku?

DNS ora ngidini CNAME ing puncak zona (example.com dhewe) - root kudu nggunakake cathetan A/AAAA. Cathetan CNAME mung katon ing subdomain kaya www.contone.com.

Suwene suwene owah-owahan DNS katon?

Saben rekaman mawa TTL (wektu kanggo urip) sing ngandhani solvers suwene kanggo cache - saka detik kanggo dina. Sawise nyunting rekaman, solvers umum tetep nglayani jawaban lawas nganti TTL kadaluwarsa, saengga panyebaran bisa nganti TTL sadurunge.
