 Hello, Chris!

I was glad to receive comments on our draft - many thanks! Some comments with 'JW' below.

Section 2, last paragraph: It might be useful to include a reference to 3GPP TS 23.221, "Architectural requirements", which shows the transition scenarios for 3GPP.

 JW: Yep, we can consider doing that. In 23.221, section 5.2 there is a short description on "Interoperability between IPv4 and IPv6 networks." However, we are describing the scenarios more precisely in this 3GPP v6ops document.

Section 3.1, third paragraph: change "comprised of" to "comprising"

 JW: OK!

Section 3.2, under I-CSCF:  typo on "operator's"
same section: change "an 3GPP" to "a 3GPP"

 JW: Yes to both. The first one seems to be a non-ASCII char.

Section 4.1, item 1), last paragraph: You may want to add a comment that this may require the use of NAT on external interfaces, when appropriate.  Also, a comment that the placement and handling of DNS servers for IPv4 / IPv6 communication has not been included in these scenarios.

 JW: That sounds like a good proposal. At least the NAT usage should be mentioned.

Section 4.1, item 4): Please define intent of the boxes marked by "x".  Are these IPv4 networks or transition gateways?

 JW: The boxes marked with "?" show that some functionality in the network would be needed to make this kind of communication possible. The needed functionality (e.g. an ALG or a protocol translator) is then described in the "3GPP analysis" document. However, it might be useful to write 1-2 sentences on the "?" box functionality also in this document...

Page 10, under Acknowledgements:  There is an unknown character after Sipil.

 JW: Yes, we shall make him Mr. Sipila. :-)

Cheers,
