Re: [v6ops] I-D Action: draft-ietf-v6ops-enterprise-incremental-ipv6-01.txt

[Arturo Servin <[e-mail]>]

	Sorry about a bit late.

	Some comments:

	Section 3.4.3 (and 4.3)

	I-D.gashinsky-v6ops-v6nd-problems is now rfc6583.

	3.5 Address plan

	I am not sure that the operation community has converged to declare
/127 for p2p links even though RFC6164. In any case, a recommendation to
use a /127 but to reserved a /64 for future use may be good to add.

	4.4 is empty. Are you planning to add text? I think you should.

	Also, some considerations from 4.4 (Applications) I think apply to 5.3
(application testing, database length fields, logging, etc.)

	6.2 IPv6-only
	
	I think you are missing an important motivation to move to IPv6 only.
This cost is in datacenter operations where admins do not need to
maintain ipv4 for applications that never interact with the end-user
(with v4), for example databases, application servers, etc. Hence there
is a saving by not maintaining double server configurations, firewalls,
etc.

	7.2 Data center virt.

	You can add some of my previous comment here as well.

Regards,
