I understand that, but the inconvenient is the fix allocation of ports per
client, and not all the clients use the same number of ports. Every option has
good and bad things.
MAP is less efficient in terms of maximizing the “use” of the existing IPv4
addresses.

Hi Jordi
My alternative to MAP-E is plain old NAT 444 dual stack. I am trying to avoid
the expense and operative nightmare of having to run a redundant NAT server
setup with thousands of users. MAP is the only alternative that avoids a
provider run NAT server.

Ask the vendor to support RFC8585.
Also, you can do it with OpenWRT.
I think 464XLAT is a better option and both of them are supported by OpenWRT.
You can also use OpenSource (Jool) for the NAT64.

Hello
Are there any known public deployments of MAP-E? What about CPE routers with
support?
The pricing on IPv4 is now at USD 20/address so I am thinking we are forced to
go the CGN route going forward. Of all the options, MAP-E appears to be the
most elegant. Just add/remove some more headers on a packet and route it as
normal. No need to invest in anything as our core routers can already do that.
No worries about scale.
BUT - our current CPE has zero support. We are too small that they will make
this feature just for us, so I need to convince them there is going to be a
demand. Alternatively I need to find a different CPE vendor that has MAP-E
support, but are there any?
What is holding MAP-E back? In my view MAP-E could be the end game for IPv4.
Customers get full IPv6 and enough of IPv4 to be somewhat compatible. The ISP
networks are not forced to do a lot of processing such as CGN otherwise
requires.
I read some posts from Japan where users are reporting a deployment of MAP-E.
Anyone know about that?
Regards,
Baldur
