ABOUT

DNS resolvers are the servers on the Internet that translate domain names into IP addresses. This tool identifies your dns resolvers so you can verify your network configuration and check for dns leaks.

DNSSEC is a mechanism by which dns responses can be authenticated. You may wish to verify proper DNSSEC usage to protect yourself from attacks such as dns cache poisoning. This tool attempts connections to domain names which are purposely configured to fail DNSSEC authentication and warns you if any of those connections is successful.

USAGE

Load https://dnscheck.tools in any web browser to identify your current dns resolvers and check DNSSEC validation.

Advanced

Combine options into a hyphen-separated string. Then make a dns request using that string as a subdomain of go.dnscheck.tools.

Answers are provided for A, AAAA, and TXT requests. Responses are signed with DNSSEC algorithms 13, 14, and 15 by default.

The https://dnscheck.tools/watch[/xxxxxx] page displays, in real time, dns requests received for subdomains containing the "watch" option and 6-character alphanumeric string xxxxxx.

Options

Subdomains may contain (hyphen-separated):
