IGS was the first Go server, written by Tim Casey and Mark Okada. (Before that, there were chess servers.) NNGS came later. It followed the IGS protocol. This allowed NNGS to get up and running quickly since it allowed reuse of existing client programs such as xgospel. But it led to trouble since IGS aggressively claimed that NNGS had no right to use the IGS protocol. KGS avoided such a fight with IGS by implementing their own protocol. Starting with the original NNGS code that was published by Erik van Riper the code was rewritten by Nils Lohner and others. This is the code that is publically available. I believe that someone told me that the NNGS server that ran on the internet did not use this code.
