SECTION 2 13. The node identifier is 0000:0000:1211 . Assuming a 32-bit subnet identifier, the subnet address is 581E:1456:2314:ABCD:0000 where ABCD:0000 is the subnet identifier. 15. 581E:1456:2314:0000:ABCD:0000:0001:XXXX through 581E:1456:2314:0000:ABCD:0000:00C8:XXXX where XXXX is the node identifier. 17. See Figure 27.1. 19. The destination unreachable message for IPv6 is almost identical to that of IPv4 with 2 exceptions: the type is type 3 in IPv4 and type 1 in IPv6 and there are far fewer possible codes in IPv6 than there were in IPv4 (5 as opposed to 16 in IPv4). 21. In the parameter problem message, the type is type 4 in IPv6 and type 12 in IPv4. In IPv4, the code could be either 0 for an error or ambiguity in one of the header fields or 1 if a required part of an option is missing. In IPv6, code 0 means the
