What is findns?

findns is a Go-based scanner that hunts for working DNS resolvers compatible with tunneling tools like DNSTT and Slipstream, testing UDP port 53 and DoH port 443 endpoints. In restricted networks where DPI blocks plain DNS, it runs a full pipeline—ping reachability, resolution speed, hijack detection, EDNS payload support, NS delegation, and optional E2E tunnel verification—to output ranked JSON results with metrics like ping_ms and edns_max. Users get a TUI for zero-config scans, CLI chains like `findns scan --domain t.example.com`, and offline mode with 7,800+ bundled regional resolvers.

Why is it gaining traction?

It stands out with 50 parallel workers blasting through thousands of candidates in minutes, auto-fetching global lists or scanning CIDR ranges like 185.51.200.0/24, plus seamless DoH support that masquerades as HTTPS traffic. The interactive TUI guides setup without memorizing flags, and E2E tests actually launch dnstt-client to confirm real connectivity, saving trial-and-error. For fast DNS resolver hunts—whether for gaming latency, VPN tunnels, or European/German servers—its JSON pipelining feeds winners into subsequent scans effortlessly.

Who should use this?

Network engineers in censored regions like Iran building DNSTT servers need it to find fast DNS addresses that evade blocks. DevOps running fast DNS VPN tunnels or testing resolvers for gaming/low-ping setups will appreciate the EDNS checks and E2E validation. Anyone scanning for findnsecure endpoints or regional fast DNS servers in Europe/Germany can use the bundled lists and CIDR tools without custom scripts.

Verdict

Grab it if you're in a DPI-heavy network—docs are thorough, Windows binaries work out-of-box, and MIT license keeps it simple. With 83 stars and 1.0% credibility score, it's early but functional for its niche; test on a small list first as maturity shows in focused features over broad polish.
