How do I use the DNS Lookup Tool?

Enter the domain name you want to inspect and run the lookup to query multiple DNS record types in one batch. Review each result table separately so you can compare address records, mail routing records, nameserver records, and TXT data. Check the TTL column to understand how long resolvers are likely to cache each answer before asking again. Use the copy button beside any individual record when you need to paste the exact value into a ticket, document, or DNS panel. Repeat the lookup after DNS changes propagate to confirm that the new public answers match your expected configuration.

Is the DNS Lookup Tool free?

Yes, the DNS Lookup Tool is completely free. It runs entirely in your browser with no signup, no download, and no data sent to any server.

TTL is the time-to-live in seconds. Higher TTL values usually mean resolvers can cache the answer longer before asking again.

How to use

How to query DNS records like A, AAAA, MX, NS, TXT, CNAME, and SOA from the browser

1 Enter the domain name you want to inspect and run the lookup to query multiple DNS record types in one batch.
2 Review each result table separately so you can compare address records, mail routing records, nameserver records, and TXT data.
3 Check the TTL column to understand how long resolvers are likely to cache each answer before asking again.
4 Use the copy button beside any individual record when you need to paste the exact value into a ticket, document, or DNS panel.
5 Repeat the lookup after DNS changes propagate to confirm that the new public answers match your expected configuration.

A DNS lookup tool is useful for troubleshooting websites, email delivery, CDN routing, and third-party verification records. Instead of using separate terminal commands for each record type, a browser tool can show the most common answers in one place with consistent formatting and fast copy actions.

Seeing TTL values matters because DNS changes are not always visible instantly. Even after you update a zone, resolvers may keep the older answer until the TTL expires. That makes a lookup tool helpful not only for identifying current records, but also for understanding why a recent DNS change may still look inconsistent across locations or devices.
