$./ircd

An IRC server needs its own addresses.

Unreal, InspIRCd, whatever you compile. Each IRCD Shell gets a dedicated IPv4 and IPv6 so you can bind 6667, 6697, 7000, and the rest. This is not a Heavy Shell with a daemon squeezed in.

IRC server: nicks, #channels, port 6667

An IRCD is an IRC server. It listens on the usual ports, accepts clients and leaves, and talks to other servers if you hub. That needs addresses you control, not a shared shell IP you share with Eggdrop and ZNC.

IRC daemons are not allowed on Heavy Shell. They go here. Heavy is still the unlimited-process Linux shell for bots, bouncers, and streaming. Different product.
