Paste raw traceroute, tracert, MTR or Cisco output and see the path instead of counting columns: every hop classified — your gateway, carrier routers, CGNAT, likely firewalls — silent hops explained, latency jumps flagged, and the perimeter boundary marked. Everything runs in your browser.
Understands Linux/macOS traceroute, Windows tracert, mtr --report, and Cisco/FortiGate CLI traceroute. Device types are heuristics from hostnames, address ranges and reply behaviour — treat them as strong hints, not gospel.
# Windows tracert -d example.com # -d skips DNS (faster); drop -d to keep names tracert example.com # Linux / macOS traceroute example.com # add -I for ICMP if UDP probes die early mtr --report --report-cycles 10 example.com # Cisco IOS / IOS-XE traceroute 203.0.113.10 # FortiGate execute traceroute 203.0.113.10
Keep hostnames in (no -d / -n) when you can — names like fw-edge or core-rtr make the device classification much sharper.
