How do servers ban IRC clients?

For example, if server bans all possible IRC clients except Mibbit,
how do they get info about client? Is it possible to mask IRC client
ident, i.e. to evade detection? Like if I  want to mask my mIRC or
AdiIRC as "Mibbit".

If I remember correctly, Mibbit connects to IRC servers through
Mibbit's servers instead of connecting directly, so the IRC servers
can just block all IP addresses that aren't Mibbit's.

As I can see each of Mibbit users have unique hashed IP addresses. If
they were connected through Mibbit servers their IP would not differ
so much.

Except, most IRCds support WebIRC (or however you want to capitalize
that) which allows a trusted gateway service, like Mibbit, to pass
through the client's IP address. So, even though the actual TCP/IP
connection to the IRCd is from Mibbit's server, the client reflects
the IP address they're using to connect to Mibbit.

Some servers are configured to show the client IP provided by Mibbit
instead of showing Mibbit's servers' addresses. Though maybe Mibbit
now directly connects clients through WebSockets.
