You can use the DNS Leak Test to check for any leaks of your DNS queries.

If you are using a VPN service provider and your original location and server are displayed in the DNS Leak Test then you have a leak. But if your IP address and location is displayed as the server you have chosen using your VPN service the you are safe and there is no leak. Know more about “What is a DNS” and what exactly is a DNS Leak.

The DNS (Domain Name System) is responsible for converting domain names into IP addresses. When you type a website in the search bar and press enter, your device would first contact a DNS server to ask for the unique IP address of the site you want to visit. If you’re not using a VPN service, this request redirects to your ISP, which would then provide you with the IP address you’re looking for. This means that your ISP has a record of which sites you're visiting and can keep tabs on your online activities.

If you use a VPN service that owns its DNS servers, this request goes to the DNS servers owned by the VPN company you are subscribed to instead of your ISP’s. As a result, your ISP (as well as the government or any other third party) will remain unaware of your online activities.

DNS leaks refer to the potential risk of your system reverting to your ISP's original DNS servers even when you’re connected to a VPN. This can happen if the VPN service you’re using isn’t robust. It may happen because your VPN is misconfigured, or the service you’re using doesn't have its own DNS servers. Because of this, I would advise you to stick to VPN services that have their own DNS servers.

Essentially, a DNS leak means that your internet traffic is leaking outside the secure VPN tunnel.for more info you can check The DNS (Domain Name System) is responsible for converting domain names into IP addresses.

Essentially, a DNS leak means that your internet traffic is leaking outside the secure VPN tunnel. When this happens, your private online data runs the risk of being exposed. To truly protect yourself from DNS leaks, it is essential to go for VPNs that not only have their own DNS servers but also have adequate measures to protect your data from DNS leaks. For instance, as per many VPN reviews, nordvpn.com has an established leak protection technology that prevents encrypted queries from going outside the secure VPN tunnel.
