kline vs gline vs zline ???

[Eckstein C.]

Can someone please explain what exactly is the difference between these
(kline, zline, gline). Any source I find, they all seem to be the same
thing; banning a user from a server/network.

What, in general (I suppose it may depend on the ircd software??), is
the difference?

And I'm pretty sure I have this right:

kline/k:line = kill line
zline/z:line = zap line
gline/g:line = global line

Is this correct?

(I know this is probably a newb question, though I've been using irc for
a while, and this is one of the few things I never really knew a whole
lot about, the difference that is.)

Thanks.

Klines are also known as K-Lines or K:lines. Klines are server bans. They only effect one server. Klines are set by local IRCops or global IRCops on their own server. They use the format of username@hostname which does not include the nickname. Klines can be temporary (until removed or the server restarts) or permanent (placed in the server's configuration file so they can only be removed by editing the server's configuration file). Only IRCops on the server that the Kline was placed can remove the Kline.

Glines are global Klines. When a Gline is set, it propagates to all of the servers on the network like a ban does. Glines are never permanent; an expiration time (in unixtime) must be specified.

On IRCds such as UnrealIRCd, the Z-line is a "powerful" ban that is performed on a user's IP address rather than the hostmask, denying access to all users from the offending IP. Z-lines may expire, but in many cases are permanent.

I am sorry it took 7 years for a response to be made to this question.
