After connected to server, Irssi can automatically change your user
mode. You can set it with /SET usermode <mode>, default is +i.
/SET resolve_prefer_ipv6 - If ON, prefer IPv6 for hosts that
have both v4 and v6 addresses.
5.5 Automatic reconnecting
If you get disconnected from server, Irssi will try to reconnect
