How a virtual LAN can better protect your home network - and the best way to get started
A virtual LAN (VLAN) can isolate devices on your network, protecting your more secure devices from less secure IoT devices. Not all ISPs allow for VLAN creation.

To create a VLAN, you need the right networking hardware. Each router/modem/switch is different, so you'll need to consult your specific hardware's documentation. VLANs can be used to isolate devices, such as creating a VLAN for IoT devices, phones and tablets, or children's devices.
Imagine you have a big house with many rooms. Each room has different things in it, like toys, books, and electronics. If one room gets messy, it won't affect the other rooms. A VLAN is like a separate room for your devices, so if one device gets hacked, it won't affect the other devices.
Analysis
What is a VLAN?
A VLAN, or virtual local area network, is a secondary network within your LAN that's isolated from the rest of your network. This separation is important because it isolates the devices. For example, if you have a primary LAN with an address scheme like 192.168.1.x, and a VLAN with an address scheme like 192.168.2.x, the VLAN cannot directly access the LAN.
How to create VLANs
Creating a VLAN depends on your specific hardware. Each router/modem/switch is different, so you'll need to consult your specific hardware's documentation. For instance, my network provider (Spectrum) doesn't allow VLANs to be created. However, some routers and modems do allow VLAN creation, and it's usually done through the device's web interface or command line interface.
Benefits of VLANs
VLANs can be used to isolate devices, such as creating a VLAN for IoT devices, phones and tablets, or children's devices. This can help protect your more secure devices from less secure IoT devices. For example, if an IoT device is hacked, since it's isolated on a VLAN, the only devices it can access are those on the same VLAN, which means your desktops, laptops, tablets, and phones are safe.
Conclusion
In conclusion, VLANs can be a powerful tool in protecting your home network from potential security threats. By isolating less secure devices from more secure ones, you can help prevent security breaches and keep your network safe.
Key points
- A VLAN is a secondary network within your LAN that's isolated from the rest of your network.
- Creating a VLAN depends on your specific hardware.
- VLANs can be used to isolate devices, such as creating a VLAN for IoT devices, phones and tablets, or children's devices.
- VLANs can help protect your more secure devices from less secure IoT devices.
If you create VLANs correctly, you can significantly reduce the risk of security breaches on your home network. This can give you peace of mind and protect your sensitive information.
If you don't create VLANs correctly, you may leave your home network vulnerable to security threats. This can lead to data breaches, identity theft, and other serious consequences.
