netmasks for aliases should all be 255.255.255.255:
alias Establish an additional network address for this interface.
This
is sometimes useful when changing network numbers, and one
wishes
to accept packets addressed to the old interface. If the
address
is on the same subnet as the first network address for this
interface, a non-conflicting netmask must be given. Usually
0xffffffff is most appropriate.
The fact that this is being enforced is not a bug.
