How To Check If Network Traffic Is Using Dns Resolver You Set

Although setting up any of these resolvers on your computer or router is a straightforward process, after changing the DNS settings, there is not an obvious way to test if the network traffic is passing through the servers you configured. If you’re switching to Cloudflare 1.1.1.1, Google Public DNS 8.8.8.8, or Cisco OpenDNS 208.67.222.222, you can quickly test your settings in at least three different ways. In this guide, you will learn the steps to ensure your network traffic is passing through the DNS servers you have previously configured.

To find out if your network traffic is getting routed through the DNS servers you’ve configured, use these steps: Once you complete the steps, check the ISP column to see the name of the DNS service you’re currently using on the test result page.

Test DNS settings on Windows 11 or 10

If you’ve previously configured custom DNS settings from Cloudflare, Google Public DNS, or Cisco OpenDNS, you can quickly check if the traffic is going through the resolver you’ve configured using the nslookup tool. To test with the nslookup command if your internet traffic is using the new DNS settings on Windows 11 or Windows 10, use these steps: Under the “Default Server field,” you’ll notice the name of the DNS service you’re using. The Address field will also indicate the DNS address that your computer uses to route the network traffic.

If you’ve changed the router settings, the nslookup won’t work because it’ll show your router IP address as the DNS server, but it doesn’t mean your traffic isn’t using the service you’ve configured. To verify your traffic is routing through the DNS servers you set on your router, use these steps: After you complete the steps, in the nslookup result, you should be able to determine the TCP/IP address the router is using to route the traffic.
