Exactly, as long as one IP is unqiue you can add it to
all your interfaces with the hope one will survive the netdev
down events :))) Note that some softwares are not happy with this.
They panic and don't know how to interprete the duplicated IPs.
The case with the hidden flag is similar, there are 2 variants:
- return HIDDEN when at least one of the IPs is hidden
- return NOT_HIDDEN when at least one of the IPs is not hidden
It even works correctly in this particular case:
Hide addresses attached to this device (assume "lo") from another
devices (assume "eth0"). Sorry for the bad english.
