            dhcp(4) indicates an address that was assigned to this
            system by a DHCP server.

            auto-configuration.

            random(6) indicates an address chosen by the system at
            random, e.g., an IPv4 address within 169.254/16, or an RFC

IpAddressStatusTC ::= TEXTUAL-CONVENTION
    STATUS     current
    DESCRIPTION
           "The status of an address.  Most of the states correspond to
            states from the IPv6 Stateless Address Autoconfiguration
            protocol.

            The preferred(1) state indicates that this is a valid
            address that can appear as the destination or source address
            of a packet.

            The deprecated(2) state indicates that this is a valid but
            deprecated address that should no longer be used as a source
            address in new communications, but packets addressed to such
            an address are processed as expected.

            The invalid(3) state indicates that this isn't a valid
            address and it shouldn't appear as the destination or source
            address of a packet.

            The inaccessible(4) state indicates that the address is not
            accessible because the interface to which this address is
            assigned is not operational.

            The unknown(5) state indicates that the status cannot be
            determined for some reason.

            The tentative(6) state indicates that the uniqueness of the
            address on the link is being verified.  Addresses in this
            state should not be used for general communication and
            should only be used to determine the uniqueness of the
            address.

            The duplicate(7) state indicates the address has been
            determined to be non-unique on the link and so must not be

            used.

            The optimistic(8) state indicates the address is available
            for use, subject to restrictions, while its uniqueness on
            a link is being verified.

            In the absence of other information, an IPv4 address is
            always preferred(1)."

    STATUS     current
    DESCRIPTION
           "The origin of this prefix.

            manual(2) indicates a prefix that was manually configured.

            wellknown(3) indicates a well-known prefix, e.g., 169.254/16
            for IPv4 auto-configuration or fe80::/10 for IPv6 link-local
            addresses.  Well known prefixes may be assigned by IANA,
            the address registries, or by specification in a standards
            track RFC.

            dhcp(4) indicates a prefix that was assigned by a DHCP
            server.

            routeradv(5) indicates a prefix learned from a router
            advertisement.

            Note: while IpAddressOriginTC and IpAddressPrefixOriginTC
            are similar, they are not identical.  The first defines how

            object is meaningful to the node.

           "The type of mapping.

            Setting this object to the value invalid(2) has the effect
            of invalidating the corresponding entry in the
            ipNetToPhysicalTable.  That is, it effectively dis-
            associates the interface identified with said entry from the
            mapping identified with said entry.  It is an
            implementation-specific matter as to whether the agent

            removes an invalidated entry from the table.  Accordingly,
            management stations must be prepared to receive tabular
            information from agents that corresponds to entries not
            currently in use.  Proper interpretation of such entries
            requires examination of the relevant ipNetToPhysicalType
            object.

            The 'dynamic(3)' type indicates that the IP address to
            physical addresses mapping has been dynamically resolved
            using e.g., IPv4 ARP or the IPv6 Neighbor Discovery
            protocol.

            The 'static(4)' type indicates that the mapping has been
            statically configured.  Both of these refer to entries that
            provide mappings for other entities addresses.

            The 'local(5)' type indicates that the mapping is provided
            for an entity's own interface address.

            As the entries in this table are typically not persistent
            when this object is written the entity SHOULD NOT save the
