Net Profile Switch is an IP network switcher which allows connecting a computer to two or more networks.

Ideal for notebook users who travel from one network location to another, it switches a computer between multiple network configurations (profiles) with one click of a button.

For example, you can switch from a static to a DHCP assigned IP address, or switch one static IP address to another. Switch a proxy server, switch SMTP-server and more. Use your computer on multiple networks with this network switcher.

Assume you have a DHCP-enabled network at your office, and a static IP address assigned to your network card at home. Every time you connect your notebook or laptop to a new local network you have to change the network-adapter settings manually.

But wouldn't it be easier to store two profiles (called 'office' and 'home') and switch between networks with these two profiles?

If you deal with two or more network locations, you can benefit from this net switcher utility that creates a profile with your configuration settings. Then you can easily switch between locations by activating a profile without restarting your laptop.
