> So for 464XLAT I will need to install a PLAT capable device(s)...
PLAT support has been around already with the traditional vendors. It's
not new.
[Jordi] NAT64 (PLAT) is there available in excellent open source
implementations. You can use VMs in big rackable servers and it gets even much
cheaper. I know there is one open source implementation of NAT444. However, the
number of NAT64 boxes that you need vs NAT444 is lower, and it will keep going
lower as more and more services in Internet are IPv6 ready and those that suck
more bw such as those video services, are already IPv6 and the increase in
their traffic keeps going up.
> as well as replace all CPE with CLAT capable devices ($$$$). I will also
need to deal with the infancy period as I will GUARANTEE that the CPE will
break badly and will create additional cost ($$$$).

> For NAT444 I just need to install NAT444 router(s) . No additional cost
for CPE or added troubleshooting as the existing CPE is fully baked. Agreed
that customers will need help with IPv6, but that will be required either way.
Also, the customer maintains a native IPv4 service (all be it NATed) until IPv4
does the dodo dance. In the end, the provider turns-off the NAT444 and disables
IPv4 on their core, which has already been enabled for IPv6 when deploying
dual-stack.
Well, you need to run the numbers on time, support and acquisition of
new revenue if you maintain NAT44, while the rest of the world (and your
competitors) are going as native IPv6 as they can.
You need to consider if it's worth taking the risk of being left behind,
or not.
[Jordi] This is the key. Make your numbers, each network is a different world.
Some questions:
1) How much cost the NAT64 vs CGN ?
2) How much traffic will move to IPv6 if you use a CPE with CLAT ?
3) How many IPv4 addresses you need using CGN vs NAT64 ? That may be a lot of
money.
4) How much you will save in helpdesk support because CGN ? (Sony today,
tomorrow some others)
5) How much you can ask your customers to contribute to the replacement of the
CPE (which cost you below 20-25 USD including logistic to ship within your
country) while offering them a dual radio and better WiFi, "faster IPv6
experience", less issues with apps because the CGN, faster LAN ports, future
proof "New Internet" connection, better security (in the WiFi and a better
firewall in the CPE), etc., etc. Is not that I like to use marketing, but it is
a fact that if you don't do, sooner or later your competitor will do, and
customers like to "upgrade" things (and everybody loves better WiFi). How many
new customers you can get from the competitor because that marketing?
All that means less investment in the operator side, which you can use to fund
the acquisition or update of CPEs (in some projects we updated the Mikrotik
rubish to OpenWRT!).
My take on this. If you really want to keep using dual-stack, fine, but don't
use CGN, you don't need that. It is way cheaper to just go into the transfers
market and get more IPv4 addresses. Problem solved (including 1-4 above).
Either way, your customers will, at some point or other, show you what
will work :-).
For me, my time is very limited, particularly on this rock we call
earth. I could spend it maintaining a CGN, but I'd rather spend it
chasing down CPE vendors to get CLAT support, or bad-mouthing Sony to
get with the program. If I have to lose a few customers in the process,
so be it. If I run out of breath before I reach my goal, well, hopefully
the work done along the way will help the next idiot that sees things
the same way I do :-).
Mark.
