7E 41 03 00 00 [header information]
D9 0A FC FE [four IP octects in network byte order] ( 217.10.252.254 )
E3 2B [port number in network byte order] ( 2b * 256 + E3 = port number 11235 )

Send a 10-byte UDP packet off to the server (at the given IP and port) in the following format:
9E 4C 23 00 00 [header information]
C8 (C8 is shorter information) CE is the more detailed information from the server)
28 18 00 00 (4 bytes of your ping value, which will be echoed back in the server response)

9E 4C 23 00 00 [standard header]
C9
0A (the current net protocol version. If it doesn't match your client's net protocol version, don't display this server, as they are incompatible)
28 18 00 00 (your ping value sent back to you)

Then come two strings, both of which are null-terminated.
Both strings contain standard key/value pairs, using FF and FE as the field delimiters. FF marks the key and FE marks the value.

There is a special key named “players” whose value contains all the players and teams, they are separated by 0x0A (newline).
