Hi,
For configuring the IP, it depends if you want to configure the PC for static or dynamic IP. For dynamic IP.s you need to have a DHCP server which will provide the IP's dynamically to the hosts. for configuring the Static IP's you need to go to the adapter properties and then to the TCP/IP properties for the same and assign the IP/Subnet Mask, Gateway, DNS IP's.
You can check the IP address by going to the command prompt and using the command " ipconfig ".
Let me know if you have any other query.
regards,
