VPNUK DNS Leak Test
Verify that your DNS resolvers align with your current connection.
What is a DNS leak?
A DNS leak occurs when your device sends DNS queries (the lookups that turn website names into IP addresses) outside the encrypted VPN tunnel. Even if your web traffic is encrypted, leaked DNS requests can expose the websites you visit to your ISP, network operator, or any on-path observer. Leaks usually happen because of misconfigured resolvers, “smart” routers, captive portals, or OS features that silently fall back to a default DNS.
- Privacy risk: DNS requests reveal your browsing history and apps’ destinations.
- Location risk: Leaks may point to resolvers in the wrong country, undermining geo-privacy.
- Integrity risk: Rogue resolvers could manipulate responses for phishing or ads.
VPNUK prevents DNS leaks by routing DNS inside the VPN, enforcing safe resolvers, and providing network-level protection that keeps your queries private. If this test flags a leak, switch to VPNUK and re-run the test.
