Re: [Wg-ipv6-guide] (TOC 7.4) NAT

[Geoff Huston <gih@telstra.net>]

It would be better if a more neutral wording was used here,
and whatever your personal opinions may be about the
use of NATs, the undeniable fact is that NAT is a very commonly
deployed technology.

---------------------------------------------
7.4 NAT

RFC1631 describes Network Address Translation (NAT). NAT allows
a network device to translate address fields in the IP packet header
as they pass through the NAT device. NAT is commonly
used in IPv4 to undertake a limited form of connectivity between
private and public address realm.

NAT is not a standardized technology for IPv6, and APNIC policies
do not require or encourage any user to deploy NAT in a IPv6 context.
