DNS Lookup
Look up DNS records (A, AAAA, MX, TXT, NS, SOA, CAA, SRV, CNAME) for any domain.
About this tool
Resolve any DNS record type for a domain using a public recursive resolver. Useful for verifying nameserver delegations, mail routing, certificate authority pinning (CAA), and service discovery (SRV).
FAQ
- Why are some answers different from `dig`?
- Different recursive resolvers may have different cache states. Use the DNS Propagation tool to compare answers across multiple public resolvers.
- What is a CAA record?
- Certificate Authority Authorization — it tells CAs which authorities are allowed to issue certificates for the domain. Missing or wrong CAA records can block legitimate cert issuance.
