DNS Lookup Tool — Query A, MX, TXT, CNAME, NS Records Free
Enter any domain name to query its DNS records in real time. Supports A, AAAA, MX, TXT, CNAME, and NS record types. Results come directly from the DNS resolver — useful for debugging email delivery, verifying domain ownership, or checking propagation.
How it works
- 1 Enter a domain name Type or paste a domain (e.g. github.com) into the input field. You do not need to include https:// or a trailing slash.
- 2 Choose a record type (optional) Leave the selector on All to fetch every common record type at once, or choose a specific type such as MX to focus the query.
- 3 Click Look up Results appear grouped by record type. Each row shows the raw record value as returned by the DNS resolver.
How lookups work
The domain name you enter is sent to the belun.app lookup service, which queries the DNS resolver on your behalf and returns the results. No queries are logged or stored. The domain itself is public information — DNS records are readable by anyone.
Frequently asked questions
- What DNS record types are supported?
- A (IPv4 address), AAAA (IPv6 address), MX (mail servers), TXT (verification and policy strings), CNAME (canonical name alias), and NS (authoritative name servers).
- Why are no records returned?
- The domain may not have that record type set, or DNS propagation may still be in progress. Try selecting 'All' to see every available record type at once.
- How fresh are the results?
- Results reflect the current state of the DNS resolver cache. TTL-based caching means very recent changes may not yet be visible — usually within minutes to a few hours depending on the record's TTL.
- Can I check a subdomain?
- Yes. Enter the full subdomain, for example mail.example.com or _dmarc.example.com, and the tool will look up records for that specific name.
- How do I verify a TXT record for Google / AWS / etc.?
- Select TXT from the type dropdown and enter your domain. The TXT records will be listed — compare the value to the one provided by the service you are verifying.
- What does MX priority mean?
- Lower numbers mean higher priority. Mail is delivered to the lowest-priority (numerically smallest) MX server first, falling back to higher numbers if it is unavailable.
