Welcome to LQ.
I've always thought that somewhere around 2, "true"*
static IP's are too difficult to administer. I always use a DHCP server to assign fixed IP's based on MAC address. Do you have that option?
I use "static" to refer only to assigned IP addresses that are implemented on the host. Others use the term to also refer to assigned IP addresses that are implemented through DHCP. I prefer to call those "fixed".
, thanks for the reminder of the difference between "RH" & "RHEL", saved me the trouble
