Using Traceroute

Path discovery tool

Traceroute shows every router hop between you and a destination. It reveals where packets are delayed or dropped.

Basic usage:

tracert 8.8.8.8           # Windows
traceroute 8.8.8.8        # Linux/Mac

Reading output:

Each line shows one router hop
Three time values show latency for each probe
Asterisks (*) mean no response from that hop

What you learn:

Path taken to reach destination
Which hop has high latency
Where packets are being dropped

Limitations:

Many routers do not respond to traceroute
Firewalls may block traceroute traffic
