No, these are two different Internet technologies. The Domain Name System (DNS) allows Internet Protocol (IP) addresses to be easily configured. As IP addresses are difficult for humans to remember, the DNS acts as an address book to find things more easily.A Virtual Private Network (VPN) is a technique for converting a public Internet connection to a private one. This means users can hide their IP addresses and gain a secure and private Internet connection by using a remote VPN server.Although DNS and VPN are different services, they can both be used to improve Internet security.
