Again, you are getting into areas the original OSI reference model,
as taught by Cisco, simply does not cover. More recent OSI documents
(e.g., Internal Organization of the Network Layer) split the network
layer into three sublayers, the bottom overlapping many descriptions
of data link:
Subnetwork Independent (subnetwork here means type of transmission system)
Subnetwork Dependent Convergence
Subnetwork Dependent Access
IP, IPX, etc., are at the subnetwork independent layer. Frame relay
(with protocol identification), AAL, LLC, etc., are at the subnetwork
dependent level. Subnetwork Dependent Convergence maps from
independent to dependent, such as ARP.
Therefore, Inverse ARP and regular ARP are layer 3 protocols. I'd
also argue they are edge signaling (i.e., control) protocols rather
than end-to-end protocols.
RARP and DHCP, however, are layer 3 management protocols.
