The Best traceroute Tools and tracert Software for 2024

The need for traceroute and tracert tools

Traceroute and tracert are invaluable network diagnostic tools used to track the path that data takes as it travels from one device to another over the internet or a local network. These tools are crucial for identifying and troubleshooting network connectivity issues, particularly when data packets experience delays or fail to reach their destination.

The primary function of traceroute (on Linux/macOS) or tracert (on Windows) is to trace the route that packets follow as they pass through routers and intermediate devices between the source and destination. By showing each hop along the way, these tools help network administrators and IT professionals pinpoint where problems are occurring. If there is network congestion, packet loss, or latency issues at a specific hop, traceroute/tracert can provide key insights into where the breakdown is happening.

Another important use case is identifying network routing inefficiencies. If data is taking an unexpectedly long or convoluted route, traceroute can help identify suboptimal paths or routing loops, allowing network engineers to adjust routing protocols or configurations to improve performance. These tools can also assist in diagnosing DNS issues by showing the time it takes for data to reach various DNS servers, which can highlight problems with DNS resolution.

Ultimately, traceroute and tracert are essential for diagnosing a wide range of network issues, whether it’s identifying slow connections, understanding routing paths, or troubleshooting connectivity problems, providing network teams with actionable insights for faster resolution.

Here is our list of the best traceroute utilities and tracert software tools:

What is traceroute or tracert?

Traceroute and tracert are two commands that run tools used for network diagnostics and help with resolving connectivity issues by tracing the paths data packets take while traveling from their origins to their destinations.

The syntaxes

On a Windows machine an admin would use the tracert command; while on a Linux or Mac OS one they would use the “traceroute” command instead. The syntaxes for the commands are:

tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

traceroute [-46dFITUnreAV] [-f first_ttl] [-g gate,…] [-i device] [-m max_ttl] [-p port] [-s src_addr] [-q nqueries] [-N squeries] [-t tos] [-l flow_label] [-w waittimes] [-z sendwait] [-UL] [-D] [-P proto] [–sport=port] [-M method] [-O mod_options] [–mtu] [–back] host [packet_len]

Although the original tools were initially conceived to run from the CLIs (Command Line Interfaces), there are now more “flashier” versions with remarkable GUIs (Graphical User Interfaces). In this article, we will explore some of the best tools for traceroute and tracert.

Screenshots of traceroute and tracert

In the image below, the tracert command is running on a Windows machine and traces the path data packets would need to traverse if it had to reach the www.yahoo.com domain.

On a Linux machine the same CLI command using the traceroute keyword syntax to trace the path to google.com would look like:

As we can see from the two images, once the command is executed, the program sends out a query across the network. This is to see which routes can be used to transport data packets between the origin machine’s network and the destination’s network.

Trivia: A tracert command from a Windows operating system machine sends out an ICMP (Internet Control Message Protocol) echo request, while a traceroute command from a Linux (or Mac) machine uses the UDP (User Datagram Protocol). The response, however, is always sent back in ICMP, regardless of what the sending host’s operating system is.

How do tracert or traceroute work?

To see how traceroute/tracert works, let us take a look at a breakdown of what occurs once a tracert or traceroute command has been sent:

• The command sends an IP packet out to the target device or network and starts monitoring for reports that are sent back in the form of replies from connected intermediary devices like routers and switches.
• The packets “hop” around from one device to the next and send back replies that help figure out their round-trip-times (RTTs). RTT is defined as the length of time taken for a packet to be sent out and then for a reply to come back confirming it has reached its intended destination.

• Whenever the packets hit a device and bounce back a reply, the admin also gets a bit of information detailing its IP address and device name (if it has one).
• Every time a packet is sent out, it is assigned a TTL (Time to Live) value that defaults to a maximum of 30 hops (but can be changed at will). We can see the advantages of the TTL by looking at what happens as the packet travels or hops across the network:

Step 1: When the first packet is sent out it is assigned a TTL of 1. When it reaches the first network device the TTL is reduced by 1 (making it 0 and hence dropping the packet) and a response is sent back to the source. This returning message will close a transport cycle allowing for the RTT to be calculated. If the replying device was the intended target, then the process ends with a “Resolved” message. If not…

Step 2: A second packet will then be sent with a TTL of 2. It passes through the device identified in Step 1 (where it loses a TTL value) and moves on to the next connected device beyond it. When it reaches a second device, it drops a TTL (making it 0) and a reply is sent back to the original host.

Step … n: The packets keep going out with increasing TTL values (until the maximum is reached) and the replies keep returning with a little more detail about the network that connects the origin and destination hosts.

Step “maximum no. of hops”: Finally, when the packet with the maximum number of hops is sent out, one of two things can be expected:

1. Either, the destination host is reached and the network path is resolved or,
2. The last packet will lose its TTL value, get dropped, and end with a “maximum number of hops reached” error message indicating the host couldn’t be reached.

A little bit more about the TTL

The TTL value determines the number of intermediate routers or other connecting devices that are going to be traversed as the packet travels towards the destination host. The traceroute/tracert command launches packets with TTL values starting at 1 and gradually increasing with each subsequent outgoing packet.

The TTL values decrease every time the packet hops to a device. Any packet whose TTL value reaches zero, is discarded and a “Time Exceeded” ICMP error message is generated and sent back to the original host.

Proceeding in this way, the networking tool uses the packets and reply messages to build a list of routers that data has to traverse through, until the destination is reached and returns an “ICMP Echo Reply” message.

How does traceroute or tracert help network admins?

Once the network path has been mapped out, a network admin can simply look at it, follow the paths that were taken by consecutive packets. They can see for themselves where the problem is (in case of non-delivery of the packets) or that everything works just as well as it should.

Then, all that remains is to fix disconnected routers and tweak the ones that have a high latency or packet loss rate.

Other great features admins can expect from Traceroute NG include:

• It detects path changes and gives due notification
• The tool allows for continuous probing that yields an iteration number for the user
• Both IPv4 and IPv6 networks are supported and can be analyzed
• The path number and trace information can be saved in a .txt log file
• It is easy to copy data from the tool’s GUI to the clipboard
• The “switch” command allows admins to alternate the probe type between ICMP and TCP
• It allows for simultaneous logging (via the logging command) as well as probing
• DNS lookup can be enabled or disabled

Why do we recommend it?

SolarWinds Traceroute NG has two big advantages: it is the product of a highly respected brand and it is free to use. This system uses both ICMP (Ping) and TCP methods to check on the connection metrics of each hop in a route to a given destination. This system can be run continuously, looking for path changes.

Who is it recommended for?

Any network manager would benefit from using this tool. Its continuous mode will raise an alert if a path changes. This is an indication that a network device is experiencing problems. So, the tool is an automated network device monitor as well as a free Traceroute package. The software runs on Windows.

SolarWinds Traceroute NG is a free tool and can be downloaded at Solarwinds.com

3. VisualRoute

For network administrators looking for an exciting little tool that can perform as well as any of the more complex traceroute tools out there, they will certainly find it all in VisualRoute. This visual traceroute network tool is a joy to use as its GUI makes work a lot of fun.

Key Features:

• Shows a route on a map: The interface shows a map as well as a table of traceroute results
• Statistics storage: Store and recall route data
• Reverse tracing: Examines a connection to a customer device
• Troubleshooting: Good for case-by-case performance analysis

VisualRoute – reporting and diagnostics at its best

Administrators can get analytics results and reports that give advice like, “In general this route offers a good throughput, with hops responding on average within 68ms. However, all hops after hop 12 in network ‘[Network for 130.117.50.246]’ respond slightly slower than average.”

Taking a look at more features, though, it becomes quite obvious that VisualRoute is indeed a serious tool:

• A graphical map of the traceroute result makes it easy to comprehend and consume the data.
• Although VisualRoute’s main purpose is to map network paths, it goes above and beyond to perform several other essential network diagnostics with more tools like:
  • Reverse tracing with remote agents so admins perform a reverse trace between two locations without actually being in either of the locations.
  • Reverse DNS lookup allows for the discovery of IP addresses behind a domain name.
  • Ping plotting to gauge and capture response times of IP addresses over a given time and have the data available in informative graphs.
  • Storage of tracert data for future reference and performance comparison.
  • Sending out of continuous tracert commands over measured time intervals makes it easy for admins to monitor any performance degradations that could occur over time.

Why do we recommend it?

VisualRoute provides a useful visual representation of all of the links in a route and also shows a world map that illustrates the source and destination of a connection. This is a useful system for examining internet connections. While the world map won’t help you with local network testing, the route graph will.

Who is it recommended for?

VisualRoute is a nice tool for use by small businesses. It is likely that larger businesses will already have connection testing utilities in their system-wide monitoring tools. This system isn’t free, so buyers should decide whether those graphics are worth paying for because without them, the free SolarWinds tool would do just as well.

4. Path Analyzer Pro

Path Analyzer Pro is a visual traceroute tool that administrators with Mac machines can use alongside their Windows brethren as it works on both platforms. It is an amalgamation of tools that, apart from the main traceroute purpose, offers features that help with performance testing, DNS, Whois, and address resolution features.

Key Features:

• Multiple platforms: Available for Windows and macOS
• Visual representation: See a line graph of path speeds per link
