How to Use Spartan 6 Ethernet Port

Hi all

I need your help.I met a problem when I use the SPARTAN-6 FPGA board (xc6slx45-csg324c).I'm currently working on a project that I need to send data from my PC to FPGA board using Ethernet port. 1. How can I assign IP to the FPGA board,if possible. or 2. How can I communicate with the FPGA board from my PC with some LED indicator

Thanks
