Sometimes I’ll do an update to some DNS setting, change the hosts file, something along those lines, and my DNS cache needs clearing for Chrome. Typically I would just restart the browser, but that can be annoying if you have a lot of windows open. I found a couple of ways to do this though without having to restart,
in the URL bar. There you will see a button that says clear host cache. Click it and you’re good to go.
Click on the dropdown menu for Chrome. Go to Tools->Clear Browsing Data. Check the option to empty the cache. Your DNS should udpate without having to restart.
