Route trace

One command to trace forward and return routes between your server and any IP, with every hop labeled: China Telecom CN2, China Unicom 9929, China Mobile CMI and more.

Run in a terminal

bash <(curl -sL ipk.me/trace) -l en 216.73.217.175
-l enReport language (follows this page)

How it works

  • Forward path (this machine → target): traceroute, mtr or tracepath runs on your machine; the hop list is sent to ipk.me to be labeled.
  • Return path (target → this machine): after the trace, a one-line command is printed for you to run on the target machine; both directions are linked and shown together.
  • Results are kept on ipk.me for 180 days; only the ones you choose to share are public, and share links expire after 15 days.
  • Each hop shows its backbone (CN2, 163, 9929, 4837, CMI, CMIN2…), location and ASN; each path ends with the detected line type, e.g. CN2 GIA or CN2 GT.
  • Works on Linux and macOS. Only hop addresses and your public IP are sent.
