### 🌐 [FREE TOOL] net-benchmark — Race Every DNS Phonebook, Pick The Fastest And Get Snappier Internet Free, No New Hardware * * * ![image](https://onehack.st/uploads/default/original/3X/2/a/2ada2d94bb5f10f284d338e173bd3d45a4c2b53a.jpeg) * * * 🌐 **Your wifi’s fine — the hidden lookup is what’s lagging you.** Every site you open, your device first asks a “phonebook” ( **DNS** ) to turn `baidu.com` into a number it can dial. Slow phonebook = slow net, even on fast wifi. ⚡ **net-benchmark** is a free tool that races every phonebook so you grab the fastest = snappier internet, $0, no new hardware. Bonus: tests the _private_ kind that hides which sites you visit. 👇 🔗 Free + open source → [GitHub](https://github.com/net-benchmark/net-benchmark) > **🧠 the trick — what this actually fixes (30 sec)** > > Calling a contact by name? Your phone secretly checks its phonebook for the number, _then_ dials. The internet’s identical: name (`taobao.com`) → phonebook ( **DNS** ) → number ( **IP** ) → site loads. > > Everyone blames their wifi when sites crawl. Half the time it’s a slow or far-away phonebook 📵. There are loads of free ones (Cloudflare, Google, AliDNS…) and the fastest _for you_ depends on where you live — no way to eyeball it. > > net-benchmark just races 'em. Pings each a bunch, hands you cold numbers: who’s quickest, who’s flaky. Pick the winner, drop it in your router/phone, done. **Free speed.** > > Also tests: > > - 🔒 **Private DNS (DoH/DoT)** — normal lookups are shouted in the open; your ISP or café wifi sees every site you check. The encrypted kind hides it. This finds which private one is _also_ fast. > - 🛡 **DNSSEC** — checks the answer wasn’t swapped for a fake number (anti-scam). > - 🌍 **Website speed too** — not just the phonebook, how fast real sites respond. > **📦 install — one line (needs Python)** > > ```bash > pip install net-benchmark > > ``` > > > 💡 `pip` = Python’s app-store-in-a-command. No `pip`? Grab Python from [python.org](http://python.org) first, it’s bundled. > **🎯 DNS commands — hunt your fastest phonebook (copy-paste)** > > ```bash > # Auto-rank the top private (DoH) phonebooks for you > net-benchmark dns top --doh --limit 5 > > # Head-to-head: race two (here AliDNS vs DNSPod) > net-benchmark dns compare 223.5.5.5 119.29.29.29 --doh --iterations 3 > > # Full benchmark, private (DoH), export to Excel > net-benchmark dns benchmark \ > --resolvers "223.5.5.5,119.29.29.29" \ > --domains "baidu.com,taobao.com" \ > --doh \ > --doh-url "https://dns.alidns.com/dns-query,https://doh.pub/dns-query" \ > --iterations 3 \ > --formats excel > > # Same but DoT + anti-fake (DNSSEC) check > net-benchmark dns benchmark \ > --resolvers "223.5.5.5,119.29.29.29" \ > --domains "baidu.com,taobao.com" \ > --dot --dnssec-validate \ > --iterations 5 --formats excel > > # Babysit DNS for 2hrs, beep if lag spikes past 150ms > net-benchmark dns monitoring \ > --resolvers "223.5.5.5,119.29.29.29" \ > --dot --interval 30 --duration 7200 \ > --alert-latency 150 > > ``` > > > 💡 `223.5.5.5` / `119.29.29.29` are just sample phonebooks (China’s AliDNS & DNSPod). Swap in any — Cloudflare `1.1.1.1`, Google `8.8.8.8`, whatever. > **🌍 website-speed commands — spot the laggy sites (copy-paste)** > > ```bash > # Race two sites > net-benchmark http compare baidu.com taobao.com --iterations 3 --show-details > > # Benchmark a pile, export CSV + Excel > net-benchmark http benchmark \ > --targets "https://www.baidu.com,https://www.taobao.com,https://www.jd.com,https://www.qq.com,https://www.163.com" \ > --iterations 3 --formats csv,excel > > # Rank by TTFB (how fast a site coughs up its first byte = first sign of life) > net-benchmark http top \ > --targets "https://www.baidu.com,https://www.taobao.com,https://www.jd.com" \ > --limit 3 --metric ttfb > > # Watch sites for 1 min, alert if slow/failing > net-benchmark http monitoring \ > --targets "https://www.baidu.com,https://www.taobao.com" \ > --interval 10 --duration 60 \ > --alert-latency 200 --alert-failure-rate 5 > > ``` > > Exports JSON / CSV / Excel / PDF — drop straight into a report or dashboard (Grafana, Prometheus). > **👤 who's this for + the numbers it spits out** > > - 🐌 Anyone whose net “feels slow” and wants _proof_ of where the lag hides > - 🏠 Home-network / Pi-hole / router folks picking the best DNS > - 🕵 Privacy people who want encrypted-but-fast lookups > - 🧑‍💻 Devs troubleshooting connections > > It doesn’t hand you the lucky-fast average — it gives **P95/P99** (the speed you get _almost always_) and **jitter** (steady vs bouncy). Real-world, not marketing. **simple-pimple:** `pip install net-benchmark` → race the phonebooks → pick the fastest → set it on your router → 🚀 free speed. Credit: author `frankovo` on GitHub.
