Finding the IP addresses of your network devices is essential for fixing network or internet problems. Most devices come with a default IP address. It’s important to know the IP of your router and switches. You can find a switch’s IP address by using the tracert command in Command Prompt. This command helps trace the path to your router, showing you the IP addresses of devices between your computer and the router1.
Key Takeaways:
Knowing the IP addresses of hardware devices is crucial for troubleshooting network or internet connection issues.
Most network devices are preconfigured with a default IP address.
Using the tracert command with the router’s IP address allows you to trace the route to the router and identify the IP addresses of the network hardware devices.
Before you start, you need to find the default gateway IP address for your network. This is the gateway that connects your local network to the internet. It helps your devices talk to other networks.
It’s key to know how to find this address for fixing network problems and getting to your router. The address varies by operating system but is easy to find.
Windows
In Windows, there are a few ways to find the default gateway IP address. One way is through the Control Panel:
Open the Control Panel.
Click on “Network and Internet” or “Network and Sharing Center”.
Select “Network and Sharing Center”.
Click on your network connection (Wi-Fi or Ethernet).
A pop-up window will appear. Click on “Details”.
Look for the “IPv4 Default Gateway” field. This shows the default gateway IP address for your network.
Or, you can use the Command Prompt:
Open the Command Prompt.
Type “ipconfig” and press Enter.
Find the “Default Gateway” field under the network you’re using. This is your default gateway IP address.
Write down this IP address for troubleshooting and getting to your router.
Using the Tracert Command to Trace the Route to the Router
Once you have the default gateway IP address, you can trace the route to the router using the tracert command in Command Prompt.
The tracert command is a key tool for fixing network problems. It helps you see the IP addresses of switches and other devices in your network by using the router’s IP address.
Running the tracert command sends out echo packets with a Time-To-Live (TTL) starting at 1. It increases the TTL by 1 for each transmission4. This helps figure out the route to the router by showing a list of hops. Each hop is a network device between your computer and the router.
The tracert command gives you IP addresses of routers’ near-side interfaces with the -d option4. It also shows the route to a destination within 30 hops4. This limit helps avoid too much network traffic or delays.
By default, tracert sends three packets to each hop for better network performance analysis5. It shows the Round Trip Time (RTT) for each hop. This tells you how long it took for the packet to get there and back5.
Tracert is great for troubleshooting big networks with many paths or parts4. It can also tell you when a router says “Destination net unreachable”4. This info is key for knowing if you can reach a network and finding problems along the way.
Tracert shows times in milliseconds for each hop, helping you understand how fast the network is5. If a hop doesn’t answer, an asterisk (*) shows up, meaning no response was received. This is often because of packet filtering or router settings5.
“Tracert can identify sub-optimal paths within an organization’s network, assisting system administrators and network engineers in optimizing traffic flow.”5
But, remember, tracert can also be used by attackers to map out a network5. This might make people want to block tracert packets5.
The tracert command gives you important info on how to get to the router. It helps you fix network problems and make traffic flow better. By using this command, you can see the path to the router and find out the IP addresses of devices in your network.
To manage and fix your network, it’s key to find the IP addresses of devices like switches and access points. This lets you link these IP addresses with the actual devices in your network. Knowing this helps you understand your network better and find devices easily for setup or fixing.
Using the tracert command is a good way to find these IP addresses. This command shows the path network packets take from your computer to a device, listing the IP addresses of devices along the way. By looking at the tracert results, you can spot the IP addresses of switches in your network.
The tracert command lists devices in the order they are found. This makes it easy to match IP addresses with devices. Knowing which devices are in your network helps you figure out which IP addresses belong to switches. This makes keeping track of your network easier and helps with future fixes.
While tracert is a strong tool for finding IP addresses, using other tools can make things better. These include:
Default IP addresses: Checking the default IP addresses of switches can give you clues for identification.
Setting laptops to the same range: Making sure laptops have IP addresses like the switches makes finding them easier.
Direct laptop connections: Connecting laptops directly to switches helps identify the IP addresses.
Network testers: Network testers can help find and identify IP addresses of network hardware.
There are also special tools for finding switch IP addresses. Tools like Cisco FindIT 2, Netgear Smartwizard Discovery, DLink Smart Console Utility, and HPE Network Discover Tool can help. These tools make finding IP addresses and matching them with devices easier.
LDWin is another tool that can help find IP addresses. It’s made for finding network hardware IP addresses. Network admins can use it to quickly find IP addresses of switches and other devices.
By following advice and using the right tools, network admins can easily find the IP addresses of network hardware. This knowledge helps them manage and fix their networks better, keeping everything running smoothly.

Cisco FindIT 2
A tool designed to facilitate switch discovery and identification of IP addresses.
One way to find switch IP addresses is by scanning the network manually. Use commands like ipconfig (for Windows) or ifconfig (for Mac or Linux). These commands show your computer’s IP address and network details. This info helps you figure out the network number and find all active IP addresses on the network through ARP scanning.
This method lets you find IP addresses without needing special tools. It gives you direct access to your computer’s network settings. This way, you avoid any issues that might come up with third-party tools.
Manual scanning is great for small networks because it’s affordable. While special tools have more features, they might not be needed for simple tasks. You can quickly get important network info using built-in commands.
“The SolarWinds IP Address Scanner is a paid product but offers a 30-day free trial.”7
But, manual scanning has its limits. It can take a lot of time in big networks with many subnets or VLANs. Also, the scan’s accuracy depends on your computer’s network settings. If these settings are wrong or missing, the scan won’t work well.
To make manual scanning better, follow a clear plan. Start by getting your computer’s IP address, subnet mask, and gateway. Then, use this info to find the network number and subnet range. Finally, do an ARP scan in the subnet to find active IP addresses.
By taking these steps, you can scan your network for IP addresses manually. This gives you important info about the devices on your network.
Advantages of Manual Network Scan
Disadvantages of Manual Network Scan
