=== Direct Client-to-Client (DCC) support ===
The Direct Client-to-Client Protocol (DCC) has been the primary method of establishing connections directly between IRC clients for a long time now. Once established, DCC connections bypass the IRC network and servers, allowing for all sorts of data to be transferred between clients including files and direct chat sessions.

==== IRCv3 SASL Mechanisms ====
IRC SASL authentication primarily uses the same mechanisms as SASL in other protocols. Most commonly:
* PLAIN as defined by [https://tools.ietf.org/search/rfc4616 RFC 4616]
* EXTERNAL as defined by [https://tools.ietf.org/html/rfc4422#appendix-A RFC 4422]
* SCRAM-SHA-256 as defined by RFC 7677
