Network Information on Your Computer

This guide explains how to identify basic network information on a computer, including local IP address, VPN IP address, and MAC address.

This information is often required for network configuration, troubleshooting, and advanced features.

What information is covered

This guide explains how to find:

• Local IP address (LAN)
• VPN IP address (if connected)
• MAC address (network hardware identifier)

Local IP address

The local IP address identifies a device inside the local network (LAN).

It is typically used for:

• Local network communication
• Network configuration
• Services running inside the same network

Common local IP ranges include:

• 192.168.x.x
• 10.x.x.x
• 172.16.x.x

VPN IP address

A VPN IP address is assigned by a VPN connection.

• It is different from the local IP address
• It exists only while the VPN is connected
• It is used for remote connectivity through the VPN

If no VPN is connected, this IP does not exist.

MAC address

The MAC address is a unique hardware identifier assigned to a network interface.

Characteristics:

• It does not change between networks
• It is used at the network hardware level
• It may be required for router or firewall configuration

Why this information matters

Knowing how to identify network information is useful when:

• Configuring a static IP address
• Troubleshooting network issues
• Verifying VPN connectivity
• Configuring network-based features
• The application cannot retrieve this information automatically
