No. Only IP addresses allocated via DHCP (server assigned) can be used. If you attempt to set a fixed IP address yourself then you may cause an IP address conflict with another system on the network if the DHCP server attempts to allocate that address. If you choose the wrong address, you could deny access to the network for several hundred other people. You must ensure your computer is configured to automatically configure its IP address via DHCP.

The IP address you are allocated will be a "private" IP which is translated to allow you to access the Internet.
