To find out what DNS server you are using, there are several methods you can use:
-
Using Command Prompt on Windows: Open the Command Prompt by clicking the Start Menu, type cmd and press Enter. Type nslookup google.com and press Enter. The line starting “Addresses” will show your DNS server address. In the example above, it’s 8.8.8.8. Alternatively, type ipconfig/all and press Enter. Look for the field labeled “DNS Servers.” The first address is the primary DNS server, and the next address is the secondary DNS server.
-
Using a website: You can visit a website such as https://www.dnsleaktest.com or http://www.whatsmydnsserver.com to see what DNS you are using.
-
Using nslookup or dig command: On desktop operating systems (Windows, macOS, Linux), you can use the nslookup command to see which DNS server is being used. The command syntax is very simple: "nslookup domainname". The first thing returned by the command is the name and IP address of the default DNS server. On macOS, you can also use the dig command to see which DNS server is being used.
-
Consulting your IT professional: If you still don’t know your DNS information, or your computer is not connected to the same network as the device you’re seeking information for, speak to a qualified IT professional at your location for assistance with finding this information.
In summary, there are several ways to find out what DNS server you are using, including using Command Prompt on Windows, visiting a website, using nslookup or dig command, or consulting your IT professional.
