Resolving DNS issues in Windows 10 and 11

DNS or Domain Name System, is the service the Internet uses to convert domain names like to a numeric IP address and connection route that your computer or device can understand. It's kind of like a giant phone book of addresses on the Internet.

Issues can sometimes arise when a site changes some DNS settings for their site. First, all of these changes need to propagate to the hundreds of thousands of DNS servers across the world, including the one your internet provider runs. And second, your local device, computer or router may store some commonly used addresses locally for a time to speed things up.

If you encounter any connection issues that may be related to DNS caching on your local end, try these steps to resolve it:

1. Restart your computer and router. The easiest way to restart your home/office router is by unplugging it for a few seconds and plugging it back in. Remember, your router is a mini-computer itself so it will take it a minute or two to come back online.

2. If this does not resolve your issue, go to Windows Search. In Windows 10, this is generally a search box right on the task bar at the bottom. In Windows 11, click on the magnifying glass icon on the taskbar.

Type in ipconfig /flushdns and hit Enter. Once this is done, restart your computer and wait about five minutes.

If you are still having issues, wait about one hour for your computer to resolve the issue itself or contact our tech support via chat or phone at 800-644-4051.
