Binding Multiple IP Address to a Single Network Card (Windows 95/98/Me) Popular

The Windows 9x GUI does not accept having multiple IP addresses specified for a single network adapter. This tweak allows you to add additional IP addresses using the registry.

This tweak can be easily applied using WinGuides Tweak Manager.

Open your registry and find the key below where the final four digits represents the network adapter. If you only have one adapter the digits will be 0000.

Within this key will be two values called "IPAddress" and "IPMask". To add additional IP addresses add the comma-separated IP and subnet mask values to both these keys respectively without using spaces.

Exit your registry and reboot for the changes to take effect.
