Below is a list of the server types available for Netrek.

Vanilla (Metaserver code B):
Also known as Bronco or Guzzler code. These servers are based on the orignal code, Terence Chang's bronco code, or Nick Trown's New Vanilla release. They are not all identical but they have minimal modifications.

Paradise (Metaserver code P):
These servers use the NetrekII/Paradise source. Paradise servers can be configured to many settings, including simulating a regular Vanilla server. The source code release includes an expanded galaxy, impluse/warp differentiation, suns, extra ships, and more. You need to use the Paradise client to play on most Paradise servers.

Hockey (Metaserver code H):
Netrek hockey mode. Most fun you can have on ice without actually being on it. Teams of players try to shoot (pressor) the Puck (a robot) into the other teams' goal.  Read more on Netrek Hockey here.

Chaos (Metaserver code C):
These servers include modifications designed to make the game chaotic, including galaxy-class ships, free plasmas, unlimited starbases, pass-through walls, and more.

Dogfight (Metaserver code F):
These are servers designed with dogfighting tournaments in mind. The code is still rather buggy, but getting better.

Base Practice (Metaserver code unknown):
These are servers designed to allow people to practice playing starbases. They feature programmable robot oggers.
