In my emails.

So it's a place to grab.

I relate "double stack" to a "coexistence" item C) in an earlier RFC
INFORMATIONAL by B. Carpenter.

With that, I can put up a draft, if you are interested to participate.

This kind of "double stack" is what many deployments do, and easier to
tell than twisting one's tongue around v6v4v6v4.

Well, I am not a native french speaker, but because you make a 
speculation on how it came up here is an explanation: I wanted to say 
"dual stack" in our email exchanges, but then I realized some people say 
"dual stack" to mean simultaneous IPv4 and IPv6 involving some 
translation/encap/DNSv4v6/sharing (RFCs like RFC6333, RFC5555, RFC4213, 
RFC4241).

On another hand, no RFC talks about "dual stack" as simultaneous use of 
IPv4 and IPv6 without any form of translation, encap, RH, DNSv4v6, 
address sharing, etc.

So I propose "double stack" for that.

At least it's clear what I talk about.

Also, if you have some other more English term to denote that, (more 
English than "double stack"), then I am willing to use it.
