2.2.1.2.5 DHCP_CLIENT_UID

The DHCP_CLIENT_UID type defines a structure that contains binary data uniquely identifying a DHCPv4/DHCPv6 client or a MADCAP lease record.

This type is declared as follows:

 typedef DHCP_BINARY_DATA DHCP_CLIENT_UID;

The DHCP_BINARY_DATA (section 2.2.1.2.9) structure contains the following members:

• DataLength: A DWORD that contains the number of bytes of data stored in the Data buffer.

• Data: A pointer of BYTE that points to an array of bytes of the length specified in DataLength. Depending on the context, it can represent any one of the following:

  • DHCPv4 client-identifier

  • DHCPv4 client unique ID

  • DHCPv6 client-identifier

  • MADCAP lease identifier

The remainder of this section explains how the preceding identifiers can be represented within the DHCP_CLIENT_UID structure.
