Traceroute Hop Latency & Network Path Tracer | iN2 Tools

Execute a network hop-by-hop trace route to map the exact internet path taken and isolate routing packet loss.

Traceroute Hop Latency & Network Path Tracer

Execute hop-by-hop packet path tracing to map intermediate routers, inspect TTL expiration responses, measure link latency, and isolate network congestion bottlenecks.

How Traceroute Packet Traversal Works

Traceroute utilizes IP Time-To-Live (TTL) header fields (RFC 791 / RFC 1393) to discover intermediate router hops along a network path. Starting at TTL=1, each router decrements the TTL; when TTL reaches 0, the router drops the packet and sends back an ICMP Time Exceeded (Type 11) message.

Interpreting Traceroute Results

  • Asterisks (* * *): Indicates a router hop that suppresses ICMP Time Exceeded responses or drops UDP/ICMP probe packets due to firewall rate limits.
  • Asymmetric Routing: Return paths from destination servers often follow different fiber routes and BGP AS-PATHs than forward paths.
  • MPLS Tunneling: Label Switched Paths (LSP) in ISP backbones may hide internal router hops.
