As a network admin, I can see no reason to remove a fixed IP address
from a NIC based on whether or not there's a carrier present. Even in
the case of DHCP, unless the address lease expires between a disconnect
and reconnect or there's pressure on the DHCP pool, most DHCP servers
will try to give a client NIC the same IP address it had when it
disconnected. Thus, even in those cases, the address "sticks".
Even if the IP address stays the same, other parameters can change. I
recently had an issue with my cable modem needing to be re-provisioned
on Comcast's network. My system did not recognize the change in DNS
servers when the modem came back up (the change from the "Walled Garden"
DNS servers to the standard ones). Took me a while to figure out what
was wrong and do a manual "ifdown" and "ifup" to get things right. With
NetworkManager, it would have been automatic.
