HostLookup

Explore DNS records and network information across public resolvers
New in version 0.2.1
Build the Android certificate verifier from source with its upstream licenses. Restrict APKs to supported ARM64 and x86_64 devices. Lock Rust dependency resolution, verify the Gradle download, and add F-Droid listing metadata, privacy disclosures, and real device screenshots.
HostLookup is a native Android DNS explorer powered by mhost.

Query 25 DNS record types, compare responses from predefined public resolvers,
and inspect individual records. Explore WHOIS, network prefixes, autonomous
system numbers, and location information for discovered IP addresses, including
nameserver and mail-server addresses.

The app uses a Material 3 interface with dynamic color on Android 12 and newer.
Android 8.0 or newer is required.

DNS queries are sent to mhost's predefined public DNS resolvers over UDP, TCP,
DNS-over-TLS, and DNS-over-HTTPS. UDP and TCP queries are unencrypted. Nameserver and mail-server address enrichment also uses the device's
configured DNS resolver. Network and location information is requested from
RIPEstat over HTTPS. Providers can see requests and your public IP address.
The public resolver list and RIPEstat service cannot be replaced in settings.

No ads, analytics SDKs, account, or HostLookup-operated server are used.
