I've posted before that we were scripting a move from ISC to Novell DHCP.
We've successfully scripted it all and are in the process of implementing
the new system now. As much as I've worked with this I haven't found an
answer about how DHCP updates it's cache when you create a new subnet or IP
address etc. I know it writes to cache when it loads but what is the
interval for updates other than at load time?
