Every domain name resolves to one or more IP addresses through DNS A (IPv4) and AAAA (IPv6) records. This tool looks up both record types for any domain, useful for troubleshooting DNS issues, verifying a domain points where you expect, or general network diagnostics.
How it works
Enter a plain domain name (not a full URL) and the tool queries DNS directly for its A and AAAA records, reporting the resolved IPv4 and IPv6 addresses found.
- Enter domain.
- Click Calculate to see your results.
Examples
Checking a domain's IP address
A domain with both A and AAAA records returns both an IPv4 and an IPv6 address — many domains today are "dual-stacked," resolving to both.
Who should use it
- Verifying a domain's DNS points to the expected server.
- General network and DNS troubleshooting.
Industry applications
- Web development and hosting/DevOps
- IT support and network administration
Advantages
- Instant lookup with no software installation.
- Checks both IPv4 (A) and IPv6 (AAAA) in one pass.
Limitations
- Shows current DNS state only — doesn't reveal DNS propagation status across every resolver worldwide.
Common mistakes to avoid
- Entering a full URL (with https:// or a path) instead of just the bare domain name.
- Expecting a raw IP address to be looked up — DNS lookups resolve a domain TO an IP, not the other way around (that's a reverse DNS lookup, a different operation).
Best practices
- If troubleshooting a "site not loading" issue, compare the resolved IP here against what you expect your DNS provider to be serving.
- Remember DNS changes can take time to propagate globally — a very recent DNS change might not show up everywhere immediately.
Tips
- Pair this with the MX Record Lookup and TXT Record Lookup tools for a fuller picture of a domain's DNS setup.
Frequently asked questions
Yes, with no signup and no limit on how many lookups you run.
That's common and not an error — many domains are IPv4-only and simply have no IPv6 (AAAA) record published.
Yes — enter the full subdomain (e.g. www.example.com or mail.example.com) just like a regular domain.
DNS records belong to a hostname, not a URL — the tool asks for just the domain (example.com) and rejects a scheme, path, or port since those aren't part of a DNS lookup.
