 **ftr** (Fast TRaceroute) is a high-performance parallel ICMP traceroute written in Rust. It sends probes concurrently for ~10x speedup over traditional traceroute, with automatic ASN lookup, reverse DNS, public IP detection via STUN, and network segment classification. Available as both a CLI tool and a Rust library. Cross-platform: Linux, macOS, Windows, FreeBSD, OpenBSD.

+Linux, BSD in 0.9.0 via PRs #38–#43; Windows in 0.10.0 via #50), each

+  `ftr` user isn't in `wheel`; run from console or `pw group mod wheel -m

+  v6, so its live multi-hop trace needs a v6-connected host. macOS
+  root-mode RAW-vs-DGRAM comparison (`sudo cargo run --release --example

+- CI gap that keeps biting: clippy runs only on Ubuntu, so `windows.rs` and
+  `bsd*.rs` dead-code/lints surface only when someone compiles those
+  targets (three separate cleanups so far). Add windows-target (and ideally
+  a BSD-target) `clippy --all-targets` cross-check to CI.
