Look up DNS records online

Features

• Nine record types: A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV
• MX priorities split out; `0 .` null MX (RFC 7505, an explicit "no mail") is explained
• TXT values reassembled from DNS presentation format, labelled SPF / DMARC / DKIM / MTA-STS / TLS-RPT
• SOA expanded into primary nameserver, mailbox, serial and the four timers
• CAA shows which CAs may issue certificates, and whether the critical flag is set
• Every record shows its TTL, with seconds converted to minutes, hours or days
• A / AAAA lookups list the intermediate CNAME chain
• NXDOMAIN and SERVFAIL get different, plain-language explanations, together with the authoritative SOA
• Switch between DNS services (Alibaba Cloud / Tencent DNSPod); falls back automatically when the primary one does not respond
• Internationalised domain names are converted to punycode automatically
• Copy the whole result at once, or download it as a text file

How to use

1. Enter a domain — pasting a full URL works too, the domain is extracted for you
2. Pick a record type and a DNS service
3. Press Run
4. Copy the result, or switch the record type and look up again

FAQ

Does the lookup go through your servers?

No. Your browser sends the query straight to Alibaba Cloud or Tencent’s public DNS service; the domain never passes through this site and we cannot see what you looked up. Open your network panel and you will see the request — it goes to `dns.alidns.com`, not to this site.

Why is a record missing, when the site loads fine?

Read the message the tool gives you first. A name that does not exist (NXDOMAIN) and an authoritative server that did not answer (SERVFAIL) are different things: the former means the name is unregistered or misspelt, the latter is often a temporary failure or a genuinely broken DNS configuration. It may also be that you asked for a record type the domain does not have — for example looking up MX on a domain that only publishes A records.

Why do the IPs come back in a different order each time?

That is normal. A domain may publish several A records, and resolvers make no promise about the order they come back in. The set is the same; only the order varies.

Do internationalised domain names work?

Yes. A Chinese or other non-ASCII domain is actually stored in DNS as punycode (starting with `xn--`); the tool converts it for you and shows the converted name in the result. To see the conversion on its own, use Punycode conversion.

Can I paste these records straight into my DNS settings?

This is a lookup result, not configuration advice. The TTLs and values can be copied as they are, but first make sure the domain is one you actually control — records read from somebody else’s domain are useless to you.
