DNS lookup
Enter a public DNS name, choose a record type and see the answer returned by Cloudflare or Google Public DNS. The name stays in the form when you change the type.
Queries go directly from your browser to the selected public DNS resolver. Use public DNS names only. Read how queries are handled.
A public-looking split-DNS name may still be confidential. Do not paste internal-only names.
Results
Enter a query and press Look up DNS.
This link includes the queried name, not saved results. Review exported DNS answers before sharing; they may contain public tokens or other sensitive-looking data.
Choose the record you need
A and AAAA provide IPv4 and IPv6 addresses. MX identifies mail exchangers; TXT carries text such as verification values or email-policy records. NS and SOA describe parts of DNS administration. CNAME names an alias target. SRV includes a service target and port, while CAA expresses certificate-authority authorization data. Enter a complete service or verification name when required, such as _dmarc.example.com. The tool does not add it silently.
Read the answer, not just the color
A returned record, no records of the requested type, NXDOMAIN and a resolver failure are different outcomes. The tool separates them and keeps the provider's response available. An alias can resolve to another name, so check the displayed path before comparing only the last IP address.
TTL and common-record checks
The TTL shown is what this resolver returned at the recorded time. It can be lower than the value configured at the DNS host because of caching. Common records performs several named queries; it does not list an entire DNS zone or discover every subdomain. A new query does not clear a resolver's cache.
Next checks
Use Compare resolvers when a change appears in one answer but not another. Use the TXT checker when a service requires an exact string. If a public answer looks correct while a local device fails, inspect that device's actual resolver, private DNS rules and application path.
