For a set of IPs in the same subnet on the same interface, wouldn't the
primary IP be the one with the proper netmask, and all IPs with netmasks
of /32 be secondary? In that situation, wouldn't deleting the primary IP
cause connection issues for the rest of the IPs?
For a set of IPs in separate subnets, each with their own non-/32
netmasks, there wouldn't really be a distinction between primary /
secondary.
