TIpStruct

Provides storage for the components of an IP address or network mask.

TIpStruct = record
  case integer of
    0: (Byte1: byte;
        Byte2: byte;
        Byte3: byte;
        Byte4: byte;);
    1: (FullAddr: Longword;);
  end;

Members

Byte1: byte;

Byte1 represents one Byte of the 4-byte IP address or network mask. Use FullAddr to access the LongWord variant of TIpStruct.

Byte2: byte;

Byte2 represents one Byte of the 4-byte IP address or network mask. Use FullAddr to access the LongWord variant of TIpStruct.

Byte3: byte;

Byte3 represents one Byte of the 4-byte IP address or network mask. Use FullAddr to access the LongWord variant of TIpStruct.

Byte4: byte;

Byte4 represents one Byte of the 4-byte IP address or network mask. Use FullAddr to access the LongWord variant of TIpStruct.

FullAddr: Longword;

FullAddr represents the IP address or network mask as a 32-bit LongWord value. Use Byte1, Byte2, Byte3, or Byte4 to access the Byte variant of TIpStruct.

Description

TIpStruct is a variant record used to store IP address values. TIpStruct has the following format:

+-------+-------+-------+-------+
| Byte4 | Byte3 | Byte2 | Byte1 | (Byte variant)
+-------+-------+-------+-------+
|           FullAddr            | (LongWord variant)
+-------------------------------+

TIpStruct provides access to the value of the IP address as a sequence of Byte values using Byte1, Byte2, Byte3, and Byte4. TIpStruct also provides access to the value of the IP address as a LongWord value using FullAddr.

TIpStruct is used by TIpProperty and the functions IP and StrToIP to store IP addresses.
