The IPv6 packet header has the following content:
ip_vtc_flow (4 bytes): // 4 bits vers., 8 bits traf. class, 20 bits flow-ID ip_plen (2 bytes): // Payload length ip_nxt (1 byte): // Next header ip_hlim (1 byte): // Hop limit ip_src (16 bytes): // Source address ip_dst (16 bytes): // Destination address
