The number of input datagrams discarded because the IPv4 address in their IPv4 header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (e.g., 0.0.0.0) and addresses of unsupported Classes (e.g., Class E). For entities which are not IPv4 routers, and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.

This object has been deprecated, as a new IP version-neutral table has been added. It is loosely replaced by ipSystemStatsInAddrErrors.
