Tip of the day: Channel mode +H provides Channel history to modern clients. Optionally, it can be stored on-disk to be preserved between server restarts.

Server protocol:Server ID

Server id's (SID's) are unique id's that identify a server. They start with a digit and are followed by 2 alphanumerical characters.
Server introductions
When a server is introduced and SIDs are enabled, the syntax is as follows:
:prefix SID servername hopcount sid :serverinfo
Example leaf introduction:
:00A SID leaf.domain.tld 2 00B :Mynetwork Leaf
Other examples of valid server IDs: 001, 0AA, 9ZZ, ..
Usage
You can (theoretically) use a SID anywhere a server name is used, like:
:server.name NOTICE #chan :Hello
Can become:
:001 NOTICE #chan :Hello
Older UnrealIRCd versions used server numerics which was a very similar feature but required base64 encoding/decoding. With SID's this is not necessary.
