About this utility

How does the DNS Leak Test work?

DNS Leak Test performs a server-side DNS check because browser JavaScript cannot directly reproduce a full resolver query from the TipsMake server environment. Enter no sensitive DNS settings; the page checks whether the authoritative collector workflow is available.

The utility reports collector availability and, when configured, the authoritative-zone context needed for real resolver observations. Compare the answer with your authoritative DNS configuration and other resolvers when troubleshooting. This utility intentionally does not invent DNS resolver results. A real leak test requires unique DNS names and an authoritative query collector controlled for the test.

Server-side DNS query

Run the query from the TipsMake server rather than pretending the browser is a full DNS client.

Record-focused output

Show the DNS answer in a format that is easy to compare with your intended configuration.

Resolver context

Explain why cache, TTL, location, or resolver choice can change the answer.

Best practices

How to get a useful DNS Leak Test result

  1. Use a public hostname you control or are authorized to troubleshoot and enter no sensitive DNS settings; the page checks whether the authoritative collector workflow is available.
  2. Check the authoritative DNS provider or zone file so you know what answer you expect.
  3. Consider TTL and resolver caching before treating a different answer as an error.
  4. Repeat from another resolver or location when users in different networks report different DNS behavior.

Important: This utility intentionally does not invent DNS resolver results. A real leak test requires unique DNS names and an authoritative query collector controlled for the test.

Questions and answers

Frequently Asked Questions

What does the DNS Leak Test tell me?

It returns collector availability and, when configured, the authoritative-zone context needed for real resolver observations. This utility intentionally does not invent DNS resolver results. A real leak test requires unique DNS names and an authoritative query collector controlled for the test.

What should I enter in the DNS Leak Test?

Use no sensitive DNS settings; the page checks whether the authoritative collector workflow is available. Enter only the information needed for the check and verify it before running the tool.

Does the DNS Leak Test send my input anywhere?

The requested network check is sent to the TipsMake server because a browser alone cannot perform the same server-side observation. Only data required for the check is used by the tool.

How accurate is the DNS Leak Test?

The tool is designed to report the calculation or observation available to its execution method. This utility intentionally does not invent DNS resolver results. A real leak test requires unique DNS names and an authoritative query collector controlled for the test.
