You need Domain Name Services (DNS) to connect to the Internet. Essentially when you type an alphanumerical Uniform Resource Locater (URL) such as http://www.cnn.com, the DNS server converts this human readable address to an Internet Protocol IP) address such as 18.104.22.168.
Most home routers use a local DNS address such as 192.168.1.1 and will pass the request for DNS services to the cable modem. The DNS address is important because you will not be able to browse the Internet if the address is incorrect.
Likewise, if you are using a virtual Private network (VPN), you don't want commonly used DNS servers to respond to your requests for an IP address.
The DNS server can log your IP address and as well as the IP address of the web site you wish to visit. This defeats the point of the VPN. In fact, there is a DNS leak test fix for Windows to make sure you VPN connection does not communicate with insecure DNS servers.
I was checking my wireless connections when I noticed my Windows wireless adapters were using the DNS addresses of 22.214.171.124 and 126.96.36.199. Have to believe some sort of stealthy malware changed the DNS addresses on my Windows PC. My PC should not have been able to browse he Internet at all, but Firfox browser has been working fine,
