And only just now realized I forgot something: DHCPINFORM is also useful
for cases where a temporary IP address is assigned through some means
other than DHCP.  The most common example of this is dial-up hosts
which use PPP and obtain their IPv4 address via IPCP.

The general rule of thumb is, if you used DHCP to obtain a leased address,
you don't need (and shouldn't use) DHCPINFORM.  It certainly isn't
appropriate for confirming a previously-leased address at reboot time;
that's what INIT-REBOOT is for.

Hope this helps...
