When using privacy services like WorldVPN, it is very important that all of your Internet traffic originating from your machine is routed through a VPN network. If any traffic is leaked outside of the VPN connection to the network, any adversary monitoring the traffic will be able to log all your activity.
Domain Name System (DNS) is used to translate domains into numerical IP addresses for instance 220.127.116.11 which are required for routing data packets on the Internet. Whenever your device contacts a server on the world wide web, such as the entered URL in your browser, your computer sends a request to a DNS server for the IP address. Most of the Internet Service Providers assign their controlled DNS servers to the customers and use them for logging and recording Internet activity made by you.
Sometimes, even when connected to the VPN network, the operating system resumes using default DNS servers instead of using anonymous DNS servers.
