Is there a way to force remote DHCPD servers to assign a different IP to 
a client with the same MAC everytime dhclient -v is called?  I've tried 
to configure the following in /etc/dhcp/dhclient.conf file and set the 
PATH_DHCLIENT_CONF=/etc/dhcp/dhclient.conf; in the current shell in an 
attempt to

supersede dhcp-lease-time 5;
supersede dhcp-rebinding-time 5;
supersede dhcp-renewal-time 5;

Or for that matter, change settings on a DHCPD servers to ensure 
everytime the same client VM requests an IP, it will be given a 
different IP vs the previous one assigned?

I've a unique scenario where I would like to also check the local DNS to 
determine if any offline hosts are already assigned to an IP and need to 
cycle through a few to determine that.

Currently the DHCPD server servers the same IP or one of two IP's 
regardless of how many times dhclient -v is called.
