			interface. In each container, there is also a list of manually
			configured addresses.
	3. IP Address YANG Module		Configuration parameters to control IP routing are defined in
			[I-D.ietf-netmod-routing-cfg].
			3. Relationship to IP-MIB
			If the device implements IP-MIB [RFC4293], each entry in the "ipv4/
			address" and "ipv6/address" lists is mapped to one ipAddressEntry,
			where the ipAddressIfIndex refers to the interface where the
			"address" entry is configured.
			The IP-MIB defines objects to control IPv6 Router Advertisement. The
			corresponding YANG nodes are defined in
			[I-D.ietf-netmod-routing-cfg].
			The objects ipNetToPhysicalTable and ipAddressStatus are writable in
			the IP-MIB but do not represent configuration, and are thus not
			mapped to the YANG module.
			The following table lists the YANG nodes with corresponding objects
			in the IP-MIB.
			+--------------------+-----------------------------------+
			| YANG node | IP-MIB object |
			+--------------------+-----------------------------------+
			| ipv4/enabled | ipv4InterfaceEnableStatus |
			| ipv4/address | ipAddressEntry |
			| ipv4/address/ip | ipAddressAddrType / ipAddressAddr |
			| ipv6/enabled | ipv6InterfaceEnableStatus |
			| ipv6/ip-forwarding | ipv6InterfaceForwarding |
			| ipv6/address | ipAddressEntry |
			| ipv6/address/ip | ipAddressAddrType / ipAddressAddr |
