Yes, VPNs can help protect against DNS (Domain Name System) leaks. DNS leaks can occur when your device uses the DNS servers provided by your ISP instead of the DNS servers provided by the VPN service. This can reveal your true IP address and location, even if you're using a VPN.
To prevent DNS leaks, many VPN providers offer DNS leak protection, which ensures that your device uses the VPN's DNS servers instead of your ISP's servers. This helps ensure that your internet traffic is encrypted and routed through the VPN server, protecting your online privacy and security.
In addition to DNS leak protection, some VPN providers also offer other features such as a kill switch, which automatically cuts off your internet connection if the VPN connection drops, preventing your IP address from being exposed. It's important to choose a reputable VPN provider that offers strong privacy and security features, and to follow best practices for using VPNs safely and securely.
