What is DNS?
DNS translates domain names (like skypath.cloud) into IP addresses. Every website visit starts with a DNS query.
Whoever resolves that query can see which domains you looked up — even if the page content is encrypted with HTTPS.

DNS Leak Test
Check whether DNS-over-HTTPS resolvers are reachable and may bypass your VPN DNS.

What this means
A DNS leak happens when domain lookups go through your ISP or local resolver instead of your VPN's DNS — revealing which sites you visit.
This browser-based check shows which public DNS-over-HTTPS resolvers are reachable from your device. It is a useful signal, not a full resolver trace.
For strongest assurance with a VPN, confirm your OS DNS settings and run this test while connected.

How VPN DNS leaks happen
Leaks often occur when the OS keeps using ISP DNS, when split tunneling sends DNS outside the VPN, or when IPv6 DNS bypasses IPv4-only VPN tunnels.
Fixes usually involve enabling the VPN's DNS setting, disabling split tunneling, or blocking non-VPN DNS in your firewall.
FAQ
What is a DNS leak?
A DNS leak is when DNS requests travel outside your VPN tunnel, exposing your browsing activity to your ISP or another third party.
Does this test prove I am safe?
This test checks browser-visible DNS behavior. A full leak assessment also depends on your OS resolver, router settings, and IPv6 configuration.
How do I fix a DNS leak?
Use your VPN app's DNS setting, disable manual DNS overrides, turn off split tunneling for DNS, and consider blocking DNS to addresses other than your VPN.
