Ip changer works great on windows vista, as that is the operating system that I used to test and create multiple network profiles. There are other programs on the market that claim to do this, but not one compares to IP Changer. The reason why I love it so much, is because it can be used with any hosting package. It will work with cPanel, FreeIP, or other web hosts that I use. It will quickly detect multiple networks and then change your IP automatically to match each one. Once you have it running, you can set up various groups, such as a home group, business group, school group, or any other group of people.
You can have different IP Changers for each group with different DNS settings, which will prevent the users in one group from accidentally visiting another site in another group.
