Section: 10.5.6.4 Packet data protocol address
Content: The purpose of the packet data protocol address information element is to identify an address associated with a PDP. The packet data protocol address is a type 4 information element with minimum length of 4 octets and a maximum length of 24 octets. The packet data protocol address information element is coded as shown in figure 10.5.137/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.155/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . Figure 10.5.137/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] : Packet data protocol address information element Table 10.5.155/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] : Packet data protocol address information element If PDP type number indicates IPv4, the Address information in octet 5 to octet 8 contains the IPv4 address. Bit 8 of octet 5 represents the most significant bit of the IP address and bit 1 of octet 8 the least significant bit. If PDP type number indicates IPv6, the Address information in octet 5 to octet 20 contains the IPv6 address. Bit 8 of octet 5 represents the most significant bit of the IP address and bit 1 of octet 20 the least significant bit. If PDP type number indicates IPv4v6: The Address information in octet 5 to octet 8 contains the IPv4 address. Bit 8 of octet 5 represents the most significant bit of the IP address and bit 1 of octet 8 the least significant bit. The Address information in octet 9 to octet 24 contains the IPv6 address. Bit 8 of octet 9 represents the most significant bit of the IP address and bit 1 of octet 24 the least significant bit. If PDP type number indicates IPv4 or IPv4v6 and DHCPv4 is to be used to allocate the IPv4 address, the IPv4 address shall be coded as 0.0.0.0.
