- Click Explain hops to see each hop annotated.
What do the symbols mean?
- * * * — The router at this hop did not respond (ICMP TTL-exceeded was blocked by a firewall or rate limiter). The route may still be working fine.
- Increasing RTT — Normal; latency accumulates with each additional hop.
- RTT spike then drop — A router is deprioritising ICMP probes but forwarding real traffic normally.
- Same IP across consecutive hops — Routing loop or MPLS tunnel not exposing inner hops.
