Hi all,

Two stateless solutions are proposed for residual deployment of IPv4 across 
IPv6-only provider services:
- draft-murakami-softwire-4v6-translation, say 4V6T 
- draft-murakami-softwire-4rd, say 4V6E (with E for encapsulation)

They both use the same stateless address mapping, i.e. that of 4rd.
It would therefore would be better, IMHO, to have:
- a separate I-D on the 4rd address mapping
- two solution I-D's pointing to it (one for 4V6T and one for 4V6E)).

Thus comments on the I-D's would better separate what relates to:
- Stateless IPv4 across IPv6-only in general (4V6)
- Stateless address mappings between IPv4 and IPv6 (4rd)
- Translation-based 4V6 (4V6T)
- Encapsulation-based 4V6 (4V6E)

Kind regards,
RD


NOTE: I really enjoyed working actively for IETF as initiator of 6rd, 4rd, and 
6a44, but, for various personal reasons including financial, I now have to 
switch to another activity. 
In particular:
- Going to Quebec won't be possible. 
- Pursuing with authorship responsibility for new 4rd drafts would have been 
too much (thanks to Tetsuya Murakami and Ole Troan for having taken over).
