Where your data goes

The hostname or IP address you enter is sent to Google Public DNS over HTTPS. sudor.io does not store the query. DNS resolvers may contact authoritative nameservers to resolve it.

Before you use the result

Enter the full selector._domainkey.domain hostname. Selectors cannot be automatically enumerated.
