It can detach the client from the actual IRC server, and also from selected channels. Multiple clients from different locations can connect to a single ZNC account simultaneously and therefore appear under the same nickname on IRC. It supports Transport Layer Security connections and IPv6.
ZNC is written in C++ and licensed under the Apache-2.0 license.
The main program, which already features multiple users, per channel playback buffers and transparent DCC bouncing, can be extended using modules. Modules can be written in Python, Perl, Tcl, or C++.{{cite web |url=https://znc.in/ |title=Official ZNC site |website=znc.in |date=2012-04-11 |access-date=2012-04-16 Available modules comprise logging functionality, Blowfish encryption, user and channel management, away functionality, a partyline and more.{{cite web |url=https://wiki.znc.in/Modules |title=Modules list on ZNC site |website=znc.in |date=2012-01-29 |access-date=2012-04-16}} A very popular module is webadmin: it provides a way to manage users and channels conveniently using only a web browser. ZNC also supports ident spoofing via oidentd.{{cite web |url=https://wiki.znc.in/Using_ident_spoofs |title=Using ident spoofs |website=znc.in |date=2012-03-25 |access-date=2012-04-16
ZNC has been in development since July 2004{{cite web |url=https://wiki.znc.in/History |title=ZNC History |website=znc.in |date=2010-06-01 |access-date=2015-01-28 |quote= psychon: znc's first commit was 2004-07-20 17:39:19 |url=https://sourceforge.net/p/znc/code/1/ |title=SourceForge revision history |website=sourceforge.net |access-date=2015-01-27 |url=https://www.openhub.net/p/znc/reviews/summary |title=ZNC on Open Hub|publisher=Black Duck Open Hub |access-date=2015-01-27 |url=http://www.irc-junkie.org/2009-12-22/irc-bouncer-comparison/ |title=IRC bouncer comparison |first=Christian “phrozen77″ |last=Lederer |publisher=IRC-Junkie.org |date=2009-12-22 |access-date=2015-01-27 |quote=Summing it up, ZNC is the winner because it is the most feature-complete and…
In mid-2009, ZNC's popularity among iPhone users increased after notification modules for Colloquy{{cite web |url=http://colloquy.info/project/wiki/PushNotifications |title=Push Notifications |website=colloquy.info |access-date=2012-04-16 |archive-date=2011-07-20 |archive-url=https://web.archive.org/web/20110720191732/http://colloquy.info/project/wiki/PushNotifications |url-status=dead |url=https://wiki.znc.in/Prowl |title=Prowl |website=znc.in |date=2011-12-17 |access-date=2012-04-16}} were published.
Since 2012, IRC clients started to integrate with ZNC: while sending channel buffers to the client, ZNC uses a timestamp indicating when each message was received, and the client shows this instead of the time when the client received the buffer. This functionality is implemented as a protocol extension.
