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
