Java Edition server software

A custom server is a Minecraft server that uses no derived code or components from the original Minecraft Classic or Survival server software, thus they are 100% free of Mojang code and restrictions. They are made as alternatives to the original server to add extra features, such as gameplay changes or to make fixes such as lag optimization. Custom servers have to stay updated to the current version of the client due to possible protocol changes, note this only applies to Beta.

Features
Custom servers have a range of features, some of which are common between them. These features extend the functionality of gameplay, administration or even many other things never thought of before in the original server.

Multiworld
Multiworld is the name of a most likely unintentional feature of the Minecraft client which can be used by a custom server. The first server to have this feature was Myne.

Usually on these servers they have a main world with portals to direct you to these other maps or by a command. They can also create new worlds and assign various properties to the world, for example; restrictions on who may enter or build on certain worlds. This makes it possible to show old worlds while still having maps for the public to build on. This can also grant more private areas to prevent grief.

Color codes
Custom servers usually take advantage of color codes (sometimes allowing players to input them with a percent instead of an ampersand)

Messages sent from the server to the client can contain color codes, which allow coloring of text for various purposes. An ampersand followed by a hex digit in the message tells the client to switch colors while displaying text.

Color coding at the start of the message will only work if the player ID byte is less than 127. If it's 127 or higher, the game automatically adds &e before the message, making it yellow. However, color codes after the first character still work. If you use an ID below 127, it doesn't add a color code, so the ones you use will work.

It is important to note that an ampersand at the end of a message that is not followed by a hex digit will crash all clients that receive it, so it is a must to sanitize chat messages received from clients.
