DNS lookup for domain troubleshooting
Use this DNS checker to inspect A, AAAA, MX, TXT, NS, and CNAME records. It helps verify website routing, email setup, SPF records, domain ownership records, and nameserver configuration.
When to use this tool
- Check A and AAAA records for website IP addresses.
- Verify MX records for mail delivery.
- Inspect TXT records for SPF, DKIM, DMARC, and verification.
- Confirm NS and CNAME records during DNS migrations.
How to read the results
- A records point a domain to IPv4 addresses.
- AAAA records point a domain to IPv6 addresses.
- MX records define mail exchangers and priority.
- NS records show authoritative nameservers for the zone.
Common DNS issues
Wrong MX: mail is routed to the wrong provider or priority.
Missing SPF TXT: email authentication may fail for sending services.
Propagation delay: cached records may differ between resolvers.
Incorrect nameservers: changes may be made in the wrong DNS zone.
Related tools
A DNS record is an entry that tells resolvers how a domain should map to IP addresses, mail servers, verification data, aliases, or nameservers.
An MX record tells other mail servers where to deliver email for a domain. Wrong MX records can stop mail delivery.
TXT records store text data used for SPF, DKIM, DMARC, domain verification, and other service configuration.
TTL is the time a resolver may cache a DNS answer before asking again. Lower TTLs can make planned changes appear faster.
Resolvers may still have cached old records, the TTL may not have expired, or the domain may be using different nameservers than expected.
