ResNet - Computer is Assigned a 192.168.x.x or 10.x.x.x IP

There are three common scenarios that can cause these symptoms:

A rogue DHCP server is overriding the computers request for a valid IP address

Most often, this happened when you, on your subnet, set up a router in your room and the DHCP server is active. Additionally, on some machines, manually assigning your IP address to 192.168.0.1 can cause your machine to act as a DHCP server for your subnet.

If you set up your computer to obtain an IP address automatically, ResNet will need to be informed immediately because in all likelihood you are not the only person affected. Please contact the DoIT Help Desk (264-HELP) right away.

You are using a private IP address

192.168.x.x and 10.x.x.x ips are two examples of a "private IP address". Private IP address implies that you will never find a computer in the Internet that has that particular IP address. If you set yourself up for a private IP address, you will be unable to use the ResNet network because of the way ResNet has your network set up. Use the ResNet documentation to reconfigure the computer to obtain an IP address automatically:

• ResNet (Windows) - Network Configuration
• ResNet (Mac OS X) - Network Configuration
