How do i find my primary and secondary DNS?
If you open a command prompt window and type ipconfig/all, the IP addresses for the two DNS servers will be shown. If you’re going through a router, odds are very good that your router’s LAN-side IP will be shown as your primary and a public address associated with your ISP will be shown as the secondary. You can manually set your DNS server addresses to your ISP’s two DNS servers (look them up on their web site), but if you’re able to get on line and your browser works, you don’t usually need to mess with the DNS settings.
