Public DNS tools
These DNS filtering tools inspect the hostname a resolver can receive, separate it from URL details, and compare records returned by two named public resolvers.
A DNS decision applies to a hostname. It does not select one page, search phrase, account screen, or file when those destinations share that hostname.
A comparison can reveal different public records or DNS response codes. It does not inspect the DNS resolver selected by your operating system, browser, router, VPN, or filtering service.

Different answers may be normal because caches, geography, and record changes affect public DNS. A matching answer does not prove that filtering is active.
It sends the same record request directly to two named DNS-over-HTTPS services and shows each response independently. HTTP errors, timeouts, and DNS response codes remain separate rather than silently falling back to another provider.
To verify a filtering policy, use the filtering provider's documented harmless test hostname from the affected device and network. Never test with a live malicious domain. This page does not discover system, router, VPN, or browser DNS settings.
