An IPv6 address using the 6to4 mode consists of an IPv4 address, the format is as the following:
2002:[a public IPv4 address in hexadecimal]::/48
For example,
A public IPv4 address is 202.156.30.41. The converted hexadecimal IP string is ca.9c.1E.29. The
IPv6 address prefix becomes 2002:ca9c:1e29::/48.

Prefix Delegation
Prefix delegation enables an IPv6 router to use the IPv6 prefix (network address) received from the
ISP (or a connected uplink router) for its LAN. The Device uses the received IPv6 prefix (for
example, 2001:db2::/48) to generate its LAN IP address. Through sending Router Advertisements
(RAs) regularly by multicast, the Device passes the IPv6 prefix information to LAN hosts. The hosts
use the prefix to generate their IPv6 addresses.
