DNS Lookup Tool
Look up A, AAAA, CNAME, MX, TXT, NS, CAA, SRV, SOA, DS, and DNSKEY records for any domain, straight from its authoritative nameservers or a public resolver.
How this lookup works
By default this tool queries the domain's own authoritative nameservers directly, the same source OneDollarDNS uses for change monitoring, so you see the live record rather than a value cached by a recursive resolver. Switch to Google, Cloudflare, Quad9, or OpenDNS to see what a public resolver currently has cached, which is useful for diagnosing propagation delays after a change.
Want to watch these records automatically instead of checking by hand? Learn about nameserver monitoring or MX record monitoring.
Have an IP address instead of a domain? Try the reverse DNS (PTR) lookup tool.
