Hi all,

I understand how to assign static IP addresses with DHCP
based on MAC. But here's what I'd like to do: I'd like to dynamically
assign an IP address to a MAC based on some rule (the rule really
is: look up this MAC in a table and give the IP address from that table,
unless it doesn't exist, in which case assign a new one and enter it
into the table). In other words, you'll get the same IP every time you
connect with the same MAC, but we don't know all MACs beforehand.


IME DHCP tends to give the same IP to the same machine unless it
gets starved for addresses and reuses it. Not sure what the underlying
rules are though.

The request for the old address comes from the client. The
DHCP server usually grants it, unless it it already leased
to somewhere else.
