I don't actually consider this to be a problem. This is how some network
IDSes are able to work (RealSecure for one) and can avoid all risk of IP
based attacks (since there's no ipaddr on the if).
But, the interfaces are able to found, you just need to look for the MAC
address and not the IP. ;-) Checking the ARP tables of your switches and
routers should bring a rogue interface that doesn't have an ipaddr assigned
to it.
