Hm, it's not really a problem:
ip address add 1.1.1.1/24 dev eth0
ip address add 1.1.2.1/24 dev eth0

Exact the same way you would do for IPv6.



Your example requires manual configuration. With IPv6, it happens automagically.

As shown here, openSUSE 12.1 does this, as does Windows 7. So, yes

I can't follow you.
The network admin makes the routing rules not the client admin.

As others have mentioned already the network staff probably wants to
track what_your_ machine is doing within the network thus they don't
allow you to use randomized addresses for a good reason.


"Out of the box" computers will be getting both addresses. This means something has to be done to prevent the network from choking on all those addresses, either change the network or change all the computers. As for knowing what's happening, the hosts advertise their presence to the entire local network, so it wouldn't be terribly difficult to match IP addresses to MAC addresses. Some people are worried about their MAC derived IP address identifying a particular computer. On the other hand, if you want to be able to reach that computer, you need a consistent IP address. Having both types addresses (sorry <g>) both situations. Use the random address for outgoing connections and the static IP for incoming.
