  ULONG  NumAdapters;
  IPAddr Address[1];
} IP_UNIDIRECTIONAL_ADAPTER_ADDRESS, *PIP_UNIDIRECTIONAL_ADAPTER_ADDRESS;

Members

The number of IPv4 addresses pointed to by the Address member.

Address[1]

An array of variables of type IPAddr. Each element of the array specifies an IPv4 address associated with this unidirectional adapter.
