ZNC is an IRC network bouncer or BNC. 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 SSL secured connections and IPv6.
ZNC is written in C++ and licensed under the GNU General Public 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++. Available modules comprise logging functionality, Blowfish encryption, user and channel management, away functionality, a partyline and more. 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.
ZNC has been in development since August 2004, and new releases are made regularly. It has received favorable reviews, especially in comparison to psyBNC, and has an active community on IRC.
In mid-2009, ZNC popularity gained momentum among iPhone users when a push module for mobile Colloquy nick highlight notifications and another module for iPhone notifications via Growl were published.
- Note: Currently at this time our ZNC provider only allows ZNC connections to our network. So if you want a ZNC to Undernet, EFnet, Rizon, etc. We cannot provide that service at this time
