IP VERSION 6 PARAMETERS Taken from [IPV6] 1. Version Number = 6 2. Traffic Class [TBD based on work of Differentiated Services W.G.] 3. Flow Label [Not a parameter] 4. Payload Length [Not a parameter] 5. Next Header 5.a. Header types 00 = Hop-by-Hop Options 43 = Routing 44 = Fragment 51 = Authentication 60 = Destination Options 50 = Encapsulating Security Payload xx = Upper Layer Header 58 = Internet Control Message Protocol (ICMP) 59 - no next header For the "xx" values see the list of protocol numbers for the values to use for the upper layer protocol (see the file: protocol-numbers). 5.b. Options Types From [IPV6]: IPv6 Option Types are 8-bit values, structured as three subfields: act - 2 bits, specifying action if Option Type is unrecognized: 00 = skip over option 01 = discard packet, silently 10 = discard packet and send ICMP 11 = discard packet and send ICMP if packet was unicast chg - 1 bit, specifying whether or not option data can change while packet is en-route: 0 = option data does not change en-route 1 = option data may change en-route rest - 5 bits, the rest of the Option Type Each distinct 8-bit Option Type identifies a different option, i.e., the high-order 3 bits are considered part of the option identification. However, it is recommended that Option Types be assigned with distinct values in the "rest" subfield, until and unless that 5-bit space becomes full. These are the currently assigned IPv6 Option Types, in order of increasing value of the "rest" subfield: b BINARY HEX act chg rest --- --- --- ----- 0 00 0 00000 Pad1 [IPV6] 1 00 0 00001 PadN [IPV6] C2 11 0 00010 Jumbo Payload [JUMBOGRAM] C3 11 0 00011 NSAP Address [RFC 1888] 4 00 0 00100 Tunnel Encapsulation Limit [TUNNEL] 5 00 0 00101 Router Alert [RFC 2711] C6 11 0 00110 Binding Update [MOBILE-IPV6] 7 00 0 00111 Binding Acknowledgment [MOBILE-IPV6] 8 00 0 01000 Binding Request [MOBILE-IPV6] C9 11 0 01001 Home Address [MOBILE-IPV6] 8A 10 0 01010 Endpoint Identification [CHARLES LYNN] 5.c.
