What is the DNS Lookup?

DNS records are the instructions that tell the internet where your domain points and how its email and services behave. This DNS lookup tool queries the live records for any domain so you can see exactly what is published right now. Check A and AAAA records to find the IPv4 and IPv6 addresses a domain resolves to, CNAME records for aliases, MX records for mail routing, TXT records for verification and SPF, and NS records for the authoritative nameservers. It is the first tool to reach for when a site will not load, email is bouncing, or you are verifying that a recent DNS change was published correctly. Results come straight from public DNS, so what you see is what resolvers see. If you have just made a change and the result looks stale, use a propagation checker, because different resolvers update on different schedules.

How to use the DNS Lookup

1. Enter the domain name you want to inspect.
2. Choose the record type (A, AAAA, CNAME, MX, TXT, NS).
3. Run the lookup to fetch live records.
4. Review the returned values and TTLs.

Common use cases

• Diagnosing why a website will not resolve
• Verifying MX and TXT records for email deliverability
• Confirming a DNS change was published correctly

Frequently asked questions

What DNS record types can I look up?

Common types including A, AAAA, CNAME, MX, TXT, and NS. A records map to IPv4 addresses, MX records route email, and TXT records hold verification and SPF data.

Why do my results look out of date after a change?

DNS changes take time to propagate and resolvers cache records for the duration of the TTL. Use a DNS propagation checker to see how the change is rolling out globally.

Is a DNS lookup the same as a WHOIS lookup?

No. DNS lookup returns the technical records for a domain. WHOIS returns registration details such as the registrar and creation date.
