I use DHCP to assign static addresses, as well as dynamic addresses, to
systems on my local network.  This makes it easy to (re)install operating
systems or make global networking changes.

With my recent install of NetBSD, I've run into problems.  I'm running the 
courier imap server, and whenever dhclient needs to renew the DHCP lease, 
it causes the imap server to stop acceping connections on the ethernt 
interface (localhost connections still work, of course, because nothing 
has happened to that interface).

What puzzles me here is that renewing an existing lease shouldn't cause 
any changes to the interface unless one or more of the network parameters 
have changed...and they haven't.

Any thoughts?  I'm not really looking for a solution (there are several 
obvious ones), as much as I'm looking for an explanation of what's going 
on.

Thanks!
