DNS Lookup
Enter a domain and choose a DNS record type. The server will resolve public DNS records and show host, value, TTL, priority, and the raw record payload.
DNS Lookup helps quickly inspect public DNS records for a domain: A and AAAA addresses, CNAME aliases, MX mail servers, TXT records for SPF/DKIM/verification, NS nameservers, SOA metadata, and CAA certificate authority policy.
This is useful when configuring a new domain, debugging email delivery, checking CDN setup, verifying ownership records, or confirming that DNS changes have propagated to the resolver used by the server.
The lookup runs server-side and displays both a readable summary and the raw DNS record payload. The tool is free, does not require registration, and is available in English and Russian.
How to use it
- Enter a domain name without a protocol, e.g. example.com or mail.example.com.
- Pick the record type: A and AAAA for IP addresses, CNAME for aliases, MX for mail servers, TXT for SPF, DKIM and verification codes, NS for name servers, SOA for zone parameters, CAA for allowed certificate authorities.
- The result shows the value, TTL and priority (for MX) together with the raw resolver payload.
When it helps
- Moving a site: check that the A record already points at the new server and read the TTL to know when everyone will see it.
- Setting up email: confirm MX points at the right service and that SPF and DKIM are published in TXT without typos.
- Domain verification: find the TXT record Google, Yandex or a certificate service asked for.
- Debugging a CDN: follow the CNAME chain to the final host.
Frequently asked questions
Why do I still see the old IP after changing the record?
Resolvers cache answers for the TTL. Until it expires part of the world keeps the previous value — that is normal and usually takes minutes to a day.
Can I look up an internal company domain?
No: the query goes to public DNS servers, which cannot see private zones.
CNAME and A at the same time — why an error?
By the standard a name with a CNAME cannot carry other records. If you need both an alias and an IP, use your provider’s ALIAS/ANAME or set the A record directly.
