See which DNS resolvers actually resolve on your behalf and where they are located.
Self-hosted authoritative DNS · takes 5-15 seconds · no third parties
How it works: the page triggers random subdomain lookups; this site's authoritative DNS (leak.netkit.tools) records the resolver IPs that actually queried on your behalf.
How to use
The page triggers random subdomain lookups; this site's own authoritative DNS (leak.netkit.tools) records the resolver IPs. Mismatched resolver locations hint at a DNS leak. Hit records are deleted after 1 hour.
