DNS Record Lookup

Published a DNS record but not sure it's propagated yet? A cached old record looks correct locally but fails at ISPs. Query any DNS record type — A, AAAA, MX, CNAME, TXT, NS, SOA — and verify what's actually resolving globally.

Understanding DNS Records

What are DNS records?

DNS records map domain names to various types of data. A records point to IP addresses, MX records route email, TXT records hold text data like SPF and DMARC policies, and NS records delegate to nameservers.

What is TTL?

Time To Live (TTL) is how long DNS resolvers should cache a record before checking for updates. Lower TTLs (300s) mean faster propagation but more DNS queries. Higher TTLs (86400s) mean better performance but slower updates.

Why check MX records?

MX (Mail Exchange) records tell the internet where to deliver email for your domain. Misconfigured MX records mean you won't receive email. Priority values determine the order servers are tried.

What are TXT records used for?

TXT records store text data for various purposes: SPF (email authentication), DMARC (email policy), DKIM (email signing keys), domain verification (Google, Microsoft), and other service configurations.
