What is my DNS server?
Run this free, instant check to see which recursive DNS servers answer lookups from this browser. No signup is required. The live result includes resolver addresses, networks, and regions.
Use this when you changed VPN DNS, enabled DNS-over-HTTPS, or need to confirm you are not still on the access ISP resolver. It is a resolver identity check, not a website speed test.
Lookups go to public leak-test endpoints from your browser. ipdet.app does not store the resolver list unless you create a report.
How to use this tool
- Connect to the network or VPN you want to inspect.
- Run the standard DNS test and wait for each source.
- Read the unique resolver table. Those IPs are the answer to “what is my DNS” for this session.

How to read the result
Each card is an independent leak-test service. If they agree on the same network, that is your current DNS path.
A VPN should usually show the provider’s resolvers or a public resolver you chose. Your home ISP appearing while the VPN is connected is the usual leak.
Troubleshoot an unexpected DNS server
First turn off browser Secure DNS / DNS-over-HTTPS and test again. Browsers can use a different resolver from the operating system or VPN.
Reconnect the VPN, flush the operating-system DNS cache, and re-run the test. If the ISP resolver remains, open the DNS leak guide for adapter and VPN-specific fixes.
Frequently asked questions
Is “whats my dns” different from “what is my DNS”?
No. Both ask which DNS servers this device is using. This page answers that with live resolver IPs rather than a static list from network settings.
Can the browser hide the system DNS?
Yes. Secure DNS / DNS-over-HTTPS in the browser can send lookups to a different provider than the OS. This test reflects what the browser used for the probe names.
Can I check my DNS without installing an app?
Yes. This test runs in the browser, requires no account, and reports the resolver that handled fresh probe names.
