To get an overview on IRC, I wanted to find out what kind of IRC server software/daemon (like unrealircd) runs on a certain server.
Is there a possibility to get this information?

In most clients you can type '/quote version' or just '/version' and it will query the server, which by default on most IRCds will respond with the info, like:
-> Odd server stuff: "351 InspIRCd-1.2 hub.yourdomain.com :FreeBSD hub.yourdomain.com 6 .2-RELEASE (InspIRCd-1.2.1) [FLAGS=0,kqueue,196]" (hub.yourdomain.com) 005 WALLCHOPS WALLVOICES MODES=19 CHANTYPES=# PREFIX=(ohv)@%+ MAP MAXCHANNELS=20 MAXBANS=60 VBANLIST NICKLEN=31 CASEMAPPING=rfc1459 STATUSMSG=@%+ CHARSET=ascii : are supported by this server 005 TOPICLEN=307 KICKLEN=255 MAXTARGETS=19 AWAYLEN=200 CHANMODES=b,k,l, BMNRcimnprstz FNC NETWORK=hubns MAXPARA=32 ELIST=MU EXTBAN=,MRNcB SAFELIST SECURELIST SSL=22.214.171.124:6697 :are supported by this server 005 STARTTLS USERIP : are supported by this server
this command tells you something about the server.
