In your previous mail you wrote:
nor Microsoft provides IPv6 support for it's OSes.
=> this is no more true!
However, some scenarios where NAT provides THE solution, are for
* private networks that may not be exposed to the Internet and
=> if you don't need a connection to the Internet then you don't even
need a NAT: I don't understand your point.
* for networks that have only one IP address available to use on the
Internet,
=> with IPv6 you can have near as many addresses as you'd like.
The restriction to one dynamic IP address should vanish (even if it is
based on not technical reasons).
I don't think NAT should be made obsolete or unneeded after IPv6 has been
deployed, but rather to be offered for some purposes on small and home
networks.
=> I disagree. IPv6 is here in order to help small and home network users
too. In fact this is very important to explain to them (even I don't know
how) that IPv6 will help them (in general they know they have a problem
but they don't know good (ie. not NAT) solutions).
Most companies and bussinesses (even small ones) will be able to
afford a dedicated Internet Connection with a couple IP addresses,
especially after IPv6 has been deployed.
=> I still cannot find a technical reason to get only a couple of addresses.
However I don't expect my ISP to provide me more than one IP address,
because I don't have a dedicated connection (yet) and I even haven't got one
static IP address (just DHCP).
=> IMHO there are two reasons to have dynamic addresses:
- the main one (well known but not technical, ie. irrelevant to these lists)
- the lack of addresses (ie. use one address per modem, not one address per
customer). This one will disappear with IPv6!
That's what's so good about NAT, from my point of view....
=> we cannot convince everybody that NAT is the devil (:-) but I have
noted NATs are not sold to small and home network users as NATs, they
are named masquerade devices, smart gateways, ...
