• The fragmentation extension header uses an IPv6 source to send packets larger than the
size specified for the path maximum transmission unit (MTU).
• The authentication extension header and the security encapsulation extension header,
used singly or jointly, provide security services for IPv6 datagrams.
Comparison of IPv4 and IPv6
Table 1: IPv4 and IPv6 differences
on page 22 compares key differences between IPv4 and
IPv6.

ICMPv6
Internet Control Message Protocol version 6 (ICMPv6) maintains and improves upon features
from ICMP for IPv4. ICMPv6 reports the delivery of forwarding errors, such as destination
unreachable, packet too big, time exceeded, and parameter problem. ICMPv6 also delivers
information messages such as echo request and echo reply.
