2.2.1.2.32 MIB_IPADDRROW

  • Article

The MIB_IPADDRROW structure specifies information for a specific IPv4 address. This structure is used in the following methods:

  • MIB_OPAQUE_INFO (section 2.2.1.2.52)

  • MIB_IPADDRTABLE (section 2.2.1.2.33) 

     typedef struct _MIB_IPADDRROW {
   DWORD dwAddr;
   DWORD dwIndex;
   DWORD dwMask;
   DWORD dwBCastAddr;
   DWORD dwReasmSize;
   unsigned short unused1;
   unsigned short wType;
 } MIB_IPADDRROW,
  *PMIB_IPADDRROW;

dwAddr: The IPv4 address.

dwIndex: The index of the interface associated with this IPv4 address.

dwMask: The subnet mask for the IPv4 address. See [RFC950].

dwBCastAddr: The broadcast address. A broadcast address is typically the IPv4 address with the host portion set to either all zeros or all ones.

dwReasmSize: The maximum reassembly size for received datagrams.

unused1: This member is reserved and SHOULD be set to 0.

wType: The address type or state.<33>
