Disable Ident lookups

[Matt Best]

Hey list, 

I'd like to disable ident lookups on my IRC server.  Is this possible
and/or a bad idea, and if so how and why?  Why does IRC need to do
ident lookups?  (I suppose I could read the RFC).

I'm using Debian Sarge with Hybrid 7.0.3-1.  

Thanks.

Kind regards, 

Matt
