About Find DNS Records
DNS (Domain Name System) records control how a domain name maps to IP addresses, mail servers, and other services. Our DNS lookup tool retrieves all DNS record types for any domain: A records (IPv4 address), AAAA (IPv6), MX (mail server), CNAME (alias), NS (nameserver), TXT records (SPF, DKIM), SOA, and PTR (reverse lookup). Essential for diagnosing email delivery problems, verifying DNS propagation after changes, checking SPF and DKIM configuration, and troubleshooting website connectivity issues.
Frequently Asked Questions
What DNS record types can I look up?
A, AAAA, MX, CNAME, NS, TXT, SOA, and PTR records are all supported.
How long does DNS propagation take?
DNS changes typically propagate within 1-4 hours, though complete global propagation can take up to 48 hours.
What is an MX record used for?
MX records specify which mail servers handle email for a domain.
What is a TXT record used for?
TXT records store text information used for email authentication (SPF, DKIM) and domain ownership verification.
Why is my DNS change not showing yet?
DNS is cached globally. Your old record's TTL value determines how long caches keep the old answer.
