Irssi IP/Hostname question

Hi there

I'm using Irssi since a few days and I feel lucky with it. I run it on
my dedicated SuSE server in conjunction with the great GNU/screen. So
when I'm connected to a IRC server, the /whois command gives me back
something like that:

21:39 -!- herr_schnegg [[email protected]]
(cut)

Is it possible to show just the hostname of my dedicated server? When
I'm connected using my desktop pc, /whois gives me back the hostname,
such as, [email protected]

Thank you for your comments!
