DHCP servers will often just revalidate the client's lease (ie, the same IP address.)
However there is NO GUARANTEE that the client will get the same lease. This is the
same with service providers, or local lans.
Bob, are you using dhcpd-2.2.x? In my debian config file there are a lot of helpful
notes (/etc/dhcpd.conf). One of them includes an example such as:
#host fantasia {
# hardware ethernet 08:00:07:26:c0:a5;
# fixed-address fantasia.fugue.com;
#}
I bet you can just comment out the hardware address and let it give the ip, or
hostname address to any computer claiming to be 'fantasia'. (if specifying a domain
name, it will be resolved first before the ip address is assigned, naturally).
