Ping & Traceroute — Network Diagnostics Guide

Master network troubleshooting with ping and traceroute. Diagnose latency, packet loss, routing issues, and connectivity problems.

Understanding Ping

Ping sends ICMP Echo Request packets and measures round-trip time in milliseconds. It tells you three things: Is the host reachable? What is the latency? Is there packet loss?

Understanding Traceroute

Traceroute reveals the entire path packets take by sending packets with incrementally increasing TTL values. Each router responds, revealing its IP and response time. This identifies exactly where problems occur.

Reading Results

Latency benchmarks:
  • Under 20ms — Excellent (local)
  • 20-50ms — Good (same country)
  • 50-100ms — Acceptable (continental)
  • 100-200ms — Fair (intercontinental)
  • Over 200ms — Poor
Packet loss: 0% is ideal, over 5% indicates a serious problem.

Common Network Problems

High latency, no packet loss: Physical distance or routing issue.

Packet loss at a specific hop: Router overload or failure.

Timeouts on all hops: Firewall blocking ICMP or destination is down.

Latency spike at one hop: Network congestion at that point.
