So far STATS has one-char parameter. The result always ends with 219 numeric ,,End of STATS report''. Whether it was empty output or invalid parameter can be determined by the char in 219 numeric (after the nickname): if it is the char we passed as parameter, the output was empty, if it was asterisk ,,*'', there was no such STATS we requested.
Note: 2.11.2 allows multi-char parameters (there's one such so far).
All examples are raw ircd output minus prefix (server name), numeric (varies from stats to stats) and nickname of a client requesting STATS. Also ending 219 numeric is omitted in whole.
Shows all succesfully loaded iauth modules and their options.

2nd field is class number or the hostname/IP mask to match the client; if NULL, it matches any class or hostname, if ``-1'', it is used only for those clients that were rejected for connecting to server-only port. 4th is server name and 5th the port, both telling the client where it should connect to.

``C'' or ``c'' (lowercase is a mark for zipped links) are connect lines, that is the list of servers we will connect to. 2nd field is remote server IP (or name), 3rd the password for connection (disguised as ``*''), 4th IRC name of a server, 5th -- port that autoconnection will be attempted to (non-positive disables A/C) and finally the class this server will be using is in 6th field.

``N'' stands for no-connect lines, and these are the servers that will connect to us. It is required that each ``C'' has its corresponding ``N''. The format is the same as ``C'' with an exception of last but one field: it is not a port, but a number of labels (parts of hostname between dots) from start to replace with ``*'' when introducing us to this server (allows masking).

Deny autoconnect to servers that names match 4th field or that are in a class specified by 5th field if any of the servers matching 2nd field or defined to be in class specified in 3rd field are currently present on the network or, if 2nd field prefixed with ``!'', denies autoconnect if none of the servers matching 2nd field is present on the network.

2nd field is an IP address, IP mask or CIDR, 3rd is password (disguised by ``*'' if present), 4th is a hostname required to match, 5th is a port this line is valid for, 6th is the class client will be put in and finally 7th field is I-line flags (all explained in the INSTALL file). 2nd and 4th fields can be prefixed by ``user@'', which means ident must match as well.
I 127.0.0.1 <NULL> <NULL> 0 10 -
The hostname or IP to match (CIDR allowed), kill line comment or (very rarely used) time interval when kill line is effective, username or auth to match, port on which kill line is effective. Lowercase ``k'' matches on auth, read the INSTALL file for more info.
K pc*.example.org sorry,no,entrance * 0 -1
The same as for ``stats K'' with one exception: field last but one shows time to live of a temporary kill line (and it always matches on all ports).

1st field is client info (client can be server, too). If uppercase ``L'' is used, then the real IP is shown, not the hostname. 2nd field is sendQ, 3rd received lines, 4th received bytes, 5th sent lines, 6th sent bytes, 7th is client uptime.

1st field is command name, the rest is in groups of 4 digits: total count, total argument bytes, remote count, remote bytes; each of 5 groups shows usage within given handler (function responsible for dealing with command coming from a given type of client), in the following sequence: server, client, oper, service, unregistered.

1st field is operator type, lowercase is local operator, uppercase is global. 2nd field is the user@hostname required to match, 3rd is password (disguised as ``*''), 4th is the nickname, 5th is port (though unused) and 6th is the class user will get after becoming operator.

1st is servername (and its socketname), 2nd is sequence number of last udp ping sent, 3rd is number of received answers, 4th is average response time in miliseconds, 5th is preference used in autoconnecting. Only last 20 minutes are remembered.
