The comparison between MAP-T and 464XLAT is not just state. With 464XLAT you can have more subscribers (almost unlimited) per IP address, without a limitation on the number of ports, so you save a lot of money in addresses. And of course, a limited number of ports in MAP-T means troubles for

I’m here ;-) I’m tracking all possible products and deployments of NAT64/DNS64/464XLAT. I’ve done a few of them myself for many customers. The idea is to bring the relevant RFCs to Internet Standards We could try to do the same also with MAP-T and others. However, my point right now

For the record, we are asking similar questions about 464XLAT in v6ops. If you are deploying it, please advise Jordi Palet Martinez. For those unfamiliar with them, MAP-T and 464XLAT are each deployment frameworks for IPv4/IPv6 translation, as described in RFCs 4164, 4166, 4167, and 7915.
