VPN’s are (typically) like an additional IP stack on your system, and can have a separate DNS server address configured.
But not all systems do this.
If your VPN does not assign a new DNS for the VPN session then you will continue to use the DNS server(s) configured in your main Internet IP Stack.
What does changing your DNS do?
DNS servers translate human-friendly domain names to machine-friendly IP addresses. You’re probably using a DNS server supplied by your ISP, one whose quality is unknown. Switching to a third-party DNS service can both speed your internet activity and protect against tricky DNS-based attacks.
Does using a VPN change your IP address?
Yes VPN changes your IP address when you try to connect to a website with the use of VPN. The request will be sent over the VPN Provider’s server. Now, the VPN Server send the request to the website server which you has requested to access. The website server open-up the communication with the VPN server.
Is changing DNS legal?
Yes, using a Smart DNS service is completely legal. If you’re not fully convinced about that, consider the following – even Google offers access to a free-to-use DNS address.
What happens if we change VPN?
When you connect to the internet through a VPN server, things change. The VPN client encrypts your data, meaning that your internet provider (ISP) won’t be able to read it. When the data reaches the VPN server, it gets decrypted and sent forward to the website you want to access.
