IPv4 and IPv6 address formats

To perform NAT 6-4 translation, the router rewrites an incoming IPv6 packet into an IPv4 address space for the source and destination of the packet. This rewrite requires that the router modify the Ethernet and the IP headers.

For more information about the IPv4 and IPv6 address formats, refer to RFC 6052 (section 2.2).
