Network Tools
Look up DNS records for a domain and inspect how it resolves across common record types.
Use this free DNS Lookup tool to check DNS records for a domain, including common records such as A, AAAA, MX, TXT, NS, and CNAME when available. It is useful for troubleshooting domain resolution, checking whether DNS changes propagated correctly, reviewing mail and nameserver setup, and understanding how a domain is configured before making infrastructure or hosting changes.

Use dns lookup when you need a fast browser-based result without extra setup. It works well for quick checks, one-off tasks, and routine formatting or calculation work.
DNS Lookup is for live technical DNS records. WHOIS Lookup is for registrar and registration-related information. If you need to know how a domain resolves right now, DNS Lookup is the better starting point.
DNS Lookup gives you a broader view of multiple record types. NS Record Lookup is narrower and focuses on delegated nameserver records. If you want a general overview first, use DNS Lookup. If your question is only about nameservers, the NS tool is more direct.
If you need to inspect delegated nameservers specifically, use NS Record Lookup. If the issue is clearly related to mail delivery, open MX Record Lookup. If you need registrar and expiration context as well, use WHOIS Lookup.

Current DNS resolution output
Helpful when troubleshooting whether record changes are visible yet.
Input
not a real domain
Output
Invalid domain or no DNS data found
The lookup fails when the domain format is invalid or cannot be resolved.
Input
simpledomain.dev
Output
Only the DNS records actually present for the domain
Not every domain has every record type, so some lookups return a partial set.
Fix: Use WHOIS Lookup for registration information and DNS Lookup for technical DNS records.
Fix: Remember that record visibility can vary because of caching, TTL, and resolver differences.
Fix: Enter a clean domain like example.com without spaces or unrelated text.
Fix: Some domains do not use every record type, so check only what is relevant to the use case.
Fix: Use NS Record Lookup or MX Record Lookup when the problem is clearly limited to one record type.
A DNS lookup shows the technical records that help a domain resolve, such as A, AAAA, MX, TXT, NS, and CNAME when those records exist.
DNS Lookup shows live DNS records, while WHOIS Lookup focuses on domain registration information such as registrar and expiration details.
Yes. It is useful for checking whether the current DNS records match the new hosting setup.
Yes. A general DNS lookup may show MX and TXT records, though MX Record Lookup is better for focused mail routing checks.
Caching, TTL values, resolver differences, and propagation timing can make DNS results vary.
DNS Lookup gives a broader DNS overview, while NS Record Lookup focuses specifically on nameserver delegation records.
Not every domain uses every record type, so the result only reflects the records that actually exist.
Yes. It is often useful for checking SPF, verification tokens, and other TXT-based records.
It is a good starting point, but MX Record Lookup is often the better next step for mail routing issues.
Use record-specific tools when the issue is clearly related to nameserver delegation or mail routing rather than general DNS visibility.
