such as the Internet. For example, if the IPv4 address is 202.124.242.22, by using IPv4-
compatible address, the IPv6 address will be ::202.124.242.22
2.4.3.2.1.5.2 IPv4-mapped Addresses
The IPv4- mapped address, 0:0:0:0:0:FFFF:w.x.y.z or
::FFFF: w.x.y.z,
is
used to represent
an
IPv4-only
node
to
an
IPv6
node.
The
example
of
IPv4- mapped
address
from
the
above example will be
::FFFF: 202.124.242.22.
2.4.3.2.1.5.3 6over4 Addresses
An address of the type [64-bit prefix]:0:0:WWXX:YYZZ, where WWXX: YYZZ is the
colon hexadecimal representation of w.x.y.z (a public or private IPv4 address),
is
used to
represent a host for the tunneling mechanism known as 6over4.
2.4.3.2.1.5.4 6to4 Addresses
An address of the type 2002:WWXX:YYZZ:[SLA ID]:[Interface ID], where
WWXX:YYZZ
is
the
colon
hexadecimal
representation
of
w.x.y.z
(a
public
IPv4
address), is used to represent a node for the tunneling mechanism known as 6to4.
