FIRCD

FIRCD is an open-source Internet Relay Chat daemon designed to operate large, scalable IRC networks. The project emphasizes a modular architecture that separates core protocol handling from features implemented as dynamically loadable modules. This design allows operators to tailor servers to their network size and policies, and to add functionality such as advanced authentication, channel moderation, and anti-abuse measures without modifying the core server.

Key features typically associated with FIRCD include support for multi-server network topologies, IPv6 and TLS encryption, configurable access control, and a plugin interface for third-party modules. The software aims to implement the core IRC protocol while enabling extensions and interoperability with common IRC services such as nick and channel services. Deployments may include integration points for automated nick registration, channel management, and operator privileges, as well as logging and auditing facilities.

FIRCD is intended for use by both small communities and large networks that require high availability. Its architecture supports modular loading of features and configurations that can be tuned for performance and reliability. The project is maintained by an open-source community, with contributions spanning core protocol handling, security hardening, and performance improvements. Releases are distributed under an open-source license, with source code hosted in a public repository.

As with other IRC daemons, FIRCD emphasizes security and operational best practices, including secure authentication, encryption in transit, and abuse prevention mechanisms. Deployments often involve load-balanced front ends, persistent storage for nick and channel data, and careful inter-server routing within networks.
