DNS Lookup queries public DNS resolvers for records associated with any domain name. It retrieves A (IPv4), AAAA (IPv6), MX (mail exchange), CNAME (canonical name), TXT (including SPF and DKIM), NS (name server), SOA (start of authority), and SRV records. Results include TTL values and are displayed in a structured table format for easy analysis of domain configuration.
System administrators managing domain configurations, DevOps engineers troubleshooting connectivity issues, and email administrators debugging delivery problems. The tool runs entirely in your browser — your data never leaves your device.
