Look up DNS records for any domain: A, AAAA, MX, NS, CNAME, and TXT records. Instant results, no signup required.
DNS (Domain Name System) translates domain names like example.com into IP addresses that computers use to connect. A DNS lookup queries name servers to retrieve records like A (IPv4 address), AAAA (IPv6), MX (mail servers), NS (name servers), CNAME (aliases), and TXT (verification and policy records like SPF).
Run this check every minute, 24/7. Get alerted by email, SMS, or webhook when something breaks.
Start Monitoring FreeWe query A, AAAA, MX, NS, CNAME, and TXT records for any domain. Each record type serves a different purpose in routing traffic, email, and domain verification.
Common causes: the domain does not exist (NXDOMAIN), your DNS registrar is down, or the domain expired. Check your registrar dashboard if records are missing.
After any DNS change, check propagation. For ongoing monitoring, Montastic can track DNS changes automatically and alert you if records change unexpectedly.
