DNS leaks are highlighted as a critical risk even when you think you’re protected by a VPN. The video explains that the Domain Name System is what translates web addresses like youtube.com into numerical IPs, and normally your ISP handles these requests, meaning they can build a detailed profile of your browsing. It emphasizes that a VPN can encrypt traffic but DNS requests may still be sent to the ISP’s DNS server if the VPN isn’t configured to route them, undermining your privacy. To fix this, the host recommends enabling a VPN’s anti-dns leak feature so DNS requests are resolved by the VPN’s servers rather than the ISP, and then testing for leaks at dedicated sites. The video also mentions alternative public DNS options like Google and Cloudflare, and notes Windows 8 and 10 users may encounter a feature that can still route to the ISP unless a fix is applied, with a plugin linked in the description to disable it. Beyond technical details, there is practical advice on assessing privacy policies from DNS providers, and a brief promo for FreshBooks is included to illustrate typical YouTube sponsorships while keeping the focus on DNS privacy. The overall takeaway is that DNS leaks can expose browsing activity even with a VPN, making proper DNS handling essential for true privacy online, along with testing and informed provider choices.
