The DHCP_IP_RESERVATION_V4 structure defines an IPv4 reservation for a DHCP client. This structure is an extension of DHCP_IP_RESERVATION (section 2.2.1.2.10) structure by including the type of client (DHCP, BOOTP or both) ([RFC2132]) holding this IPv4 reservation. This structure is used in the DHCP_SUBNET_ELEMENT_DATA_V4 (section 2.2.1.2.35) structure.

 typedef struct _DHCP_IP_RESERVATION_V4 {
   DHCP_IP_ADDRESS ReservedIpAddress;
   DHCP_CLIENT_UID* ReservedForClient;
   BYTE bAllowedClientTypes;
 } DHCP_IP_RESERVATION_V4,
  *LPDHCP_IP_RESERVATION_V4;
