Index X - Server IP

server: 171.64.122.117:8080
This is the IP and port address of the data server from which the work unit was downloaded. It is also the address to which the unit must eventually be uploaded if it is still active.

The Server IP for Folding@Home clients before v3.0 the value was stored at 040 bytes from the start of each queue index. Starting at byte 264 of each index is the Server IP for client v3.0 and later. The v3.0 and later clients also store the port number.

                u32     svr2;           /* 264 Server IP address */
