IP Address Format
A single format is used to specify IPv4 and IPv6 addresses, IPv4-mapped IPv6 addresses:
- If the intended address is IPv6, the standard “network byte order” or big-endian byte encoding is used.
- If the intended address is IPv4, the first 12 bytes are set to 0x00000000000000000000FFFF, followed by the big-endian IPv4 address.
