What is dnstt-resolver-probe?

This Python tool probes DNS resolvers to find ones compatible with DNSTT tunneling, benchmarking liveness, payload stability, and real tunnel performance. It runs a fast parallel DNS scan to filter candidates, then optional deep tests launching the official DNSTT client to verify SSH or SOCKS tunnels and auto-select optimal MTU. Users get a single CSV or XLSX report ranking resolvers for tools like HTTP Injector, solving the pain of flaky DNS in DNSTT setups.

Why is it gaining traction?

Unlike basic ping tools, it mimics real DNSTT queries—checking EDNS sizes, NXDOMAIN handling, and tunnel-domain responses—to spot resolvers that actually work, not just respond. Tuned for HTTP Injector compatibility, it handles MTU selection and logs DNSTT client output per resolver, saving hours of manual trial-and-error. Devs grab it for the quick CLI like `python dnstt_resolver_probe.py --dns-list list.txt --run-deep`, with lite mode needing zero config.

Who should use this?

DNSTT server operators hunting reliable DNS resolvers amid censorship blocks. HTTP Injector users tweaking configs for stable tunnels. Network engineers benchmarking resolver lists for DNSTT client or server github deployments.

Verdict

Solid niche probe for DNSTT workflows—grab it if you're in that world, as the FAST mode alone filters effectively. With 42 stars and 0.70% credibility score, it's early but docs are clear and single-script setup keeps it low-risk; test on your list before production.
