Ping vs Traceroute (Tracert): Difference, Commands & Network Troubleshooting Examples

Last Update: October 27, 2026 Post Views: 16

Ping checks network connectivity, while Traceroute helps identify the network path between two devices. Learn how these commands work, how network engineers use them to troubleshoot real-world internet connectivity problems.


What Is the Ping Command and How Does It Work?

Ping is a network troubleshooting command used to check whether a destination device is reachable or not. When you execute Ping, your computer sends an ICMP Echo Request and waits for an ICMP Echo Reply. Reply.

Packet Loss and Latency

Ping provides two important pieces of information:

  • Packet Loss: The percentage of Ping packets sent without receiving replies.
  • Latency: The time taken for a packet to reach the destination and receive a reply, measured in milliseconds (ms).

Example: If Ping sends 4 packets and receives all 4 replies, packet loss is 0%.

High latency, such as 200 ms or 500 ms, may indicate a network performance problem.

Ping Command Example: Checking Internet Connectivity

Suppose a user reports that the internet is not working. First, we will open Command Prompt and execute the following command:

ping www.google.com

Suppose the result shows:

  • Packets Sent: 4
  • Packets Received: 4
  • Packets Lost: 0
  • Packet Loss: 0%

This means all four packets received replies, and the Ping test was successful.

If Ping fails, possible reasons include an internet connection problem, a router issue, a routing problem, or a destination that is not responding.

Remember: Ping helps us check reachability, packet loss, and latency.


What Is Traceroute (Tracert) and How Does It Work?

Tracert is a network troubleshooting command used to identify the network path from the source device to the destination. In Windows, we use the tracert command.

Understanding Network Hops

A hop represents a router encountered along the network path. For example, the path from your computer to a Google server may look like this:

Computer → Home Router → ISP Routers → Google Server

Tracert displays the responding hops and their probe response times.

If latency increases significantly at one hop and remains high at subsequent hops, it may indicate a network performance issue along that part of the path.

How Tracert Works: TTL Mechanism

Tracert uses ICMP Echo Request probes with increasing TTL values to discover the network path. TTL stands for Time to Live.

  1. TTL = 1: The first router drops the probe packet and sends an ICMP Time Exceeded message back to the source, revealing its IP address.
  2. TTL = 2: The second router sends back an ICMP Time Exceeded message.
  3. TTL = 3: The process continues to the third router and subsequent hops.
  4. Destination Reached: Tracert continues increasing the TTL until the destination responds or the maximum hop limit is reached.

This process allows Tracert to identify the responding routers along the path to the destination.


Ping vs Tracert: Key Differences

Feature Ping Tracert
Purpose Checks destination reachability. Identifies the network path from source to destination.
Latency Measures response time to the destination. Shows response times for individual hops.
Packet Loss Reports unanswered Ping packets. Shows hops where probes do not receive replies.
Command ping www.google.com tracert www.google.com
Use Case Troubleshoots connectivity between source and destination. Helps investigate routing issues and delays along the network path.

Frequently Asked Questions About Ping and Tracert

1. What is Ping?

Ping is a network troubleshooting command used to check whether a destination device is reachable.

2. How does Ping work?

Ping sends an ICMP Echo Request and waits for an ICMP Echo Reply.

3. What is Tracert?

Tracert is a network troubleshooting command used to identify the network path from the source to the destination.

4. How does Tracert work?

Tracert uses ICMP Echo Request probes with increasing TTL values to discover the network path and identify responding routers.

5. What is the default maximum number of hops for Tracert?
