DNS Lookup
Look up A, AAAA, MX, TXT, NS, CNAME and SOA records for any domain — free. Queries authoritative nameservers for instant, uncached results — perfect for domain migration, email deliverability diagnostics and DNS propagation tracking.
The internet’s phone book
DNS (Domain Name System) translates human-readable domains like keydal.net to IP addresses like 185.x.x.x. Each record type has a specific purpose: A and AAAA map a hostname to IPv4/IPv6, MX decides which server receives email, TXT carries SPF/DKIM/DMARC authentication records, NS points to authoritative nameservers, and SOA holds zone start-of-authority metadata.
After a DNS change, old answers may remain in caches until TTL expires. Global propagation typically takes anywhere from 15 minutes to 48 hours.
About DNS lookups
It depends on TTL. TTL of 300s means 5 minutes; 86400s means 24 hours. Large ISP resolvers and public resolvers like 8.8.8.8 cache the old answer until TTL expires. This tool bypasses caches by querying authoritative nameservers.
Per RFC 5321, if MX is missing senders fall back to the A/AAAA record. This is fragile — always define an explicit MX in production.
All three are email-security records. SPF defines which servers may send mail on your behalf, DKIM adds a cryptographic signature to prove authenticity, and DMARC tells receivers what to do when SPF/DKIM fail. A correct setup dramatically reduces spam-folder delivery.
A points a hostname directly to an IP. CNAME is an alias to another hostname — resolution is delegated to that name. Per RFC 1034, CNAME cannot be used at the zone apex (@ / root); use ALIAS/ANAME instead.
