No, there's no need to have a subnet configured for an interface that
the server isn't listening on.

It would be a nightmare otherwise, in my case, as the eth2 interface is
connected to the internet with a dynamic ip, and it often changes
networks.

I'll try to be a little more specific: if you want dhcpd to accurately assign addresses to requests coming in on any or nearly any interface, what I was told by some of its maintainers just a few days ago is that the correct procedure is to let dhcpd know about any and all statically-configured subnets on that box. For example, even if I don't assign IP addresses on my Internet link with a static IP address, dhcpd would like me to let it know about that subnet anyway to avoid confusion (subnet without range).


Better for you that way?
