A loopback IP address is a special address that allows a computer to send data to itself, essentially creating a virtual network interface within the device

To create a network loopback with a specific IP address (e.g., 100.5.83.5), you’re essentially assigning a static IP to a virtual network interface (loopback-style) that routes only within the local machine.

Install Microsoft Loopback Adapter:

• Press Win + R, type: hdwwiz, press Enter.
• Click Next > choose Install hardware manually > Network adapters > Click Next.
• Choose Microsoft > Microsoft KM-TEST Loopback Adapter.
• Finish the wizard. A new virtual adapter will be added.

Assign Static IP to the Loopback Adapter:

• Go to Control Panel > Network and Sharing Center > Change adapter settings.
• Right-click the Loopback Adapter > Properties > Internet Protocol Version 4 (TCP/IPv4) > Properties.
• Set:
  • IP Address: 100.5.83.5
  • Subnet: 255.255.255.0
  • Leave gateway and DNS blank (unless needed).

Verify:

ping 100.5.83.5

It should respond immediately, indicating it’s reachable locally.
