Configure Stateless IP/ICMP Translation
Stateless IP/ICMP Translation (SIIT) is a transition mechanism algorithm that translates
between IPv4 and IPv6 packet headers. Using SIIT, an IPv6 device that does not have a
permanently assigned IPv4 addresses can communicate with an IPv4-only device.
SIIT functions with IPv4-translated addresses, which are addresses of the format
0::ff
ff:0:0:0/96 for IPv6-enabled devices. You can substitute an IPv4 address in the format
