Our new laptops come with a docking station so each laptop has three wired interfaces, and depending on how the laptop is connected, they all get a different ip, which makes finding the laptop a challenge, to say the least.

For DHCP, it's peanuts to configure the same IP for multiple mac addresses. I can't think of situations where users will try to connect two cables to the same laptop. And even if they do, so what?

Would it be possible to configure this in the foreman?
