Deborah
Thanks so much for your informative and positive message.
I have not followed the OPs area too much, but will make an effort to do so now. Any specific drafts you might suggest, I will review. In particular, I am interested in what specific IPv6 document from the OPs area you refer too?
I took a look at the ISOC IPv6 doc you listed. Interesting but it appears to be quite old. Do you feel it is still relevant? Enterprises need a lot of info on IPv6 and I want to point them in the most effective directions.
By increasing visibility, do you mean ways to get Enterprises more involved or aware of IETF? I can sadly say none that have yet been effective, but I do intend to keep trying. Perhaps you have ideas?
And finally, I checked out your Pragmatic Link. Still laughing, even though it unfortunately seems to have very little relevance to my world 😊
Once again I really appreciate your constructive comments and information.
Mike

As Barbara builds her confidence for the IETF list and while we have Mike's attention-
Mike, you commented "More, it is a lack of understanding of how things work within Enterprise Networks and the lack of Enterprise engagement in Standards Development processes. And finally, this may not be a gap that the IETF should care about or address, but someone should, IMHO."
I wanted to +1 on to Barbara's message - many of us will say - "we do care". As IETF is "huge" (for many operators/users that is the biggest bottleneck on participating), not sure if you follow the ops area (I'm a routing AD, but ops always has my attention😊), they have several documents on enterprises. Currently a document on the impact of TLS1.3 on operational network security practices. They also have an IPv6 one. I think in all the Areas (I know best the routing area), we encourage operators and users to participate. If you have suggestions - we are interested.
How to increase visibility? Do you have suggestions? Liaisons? ISOC? When RFC7381 (Enterprise IPv6) was done, it was an ISOC blog:
https://www.internetsociety.org/blog/2014/10/new-rfc-7381-enterprise-ipv6-deployment-guidelines/
Possibly this draft should be a blog? Suggestions?
Thanks again for the interesting thread- Deborah for some humor - I'm still stumbling on the draft's requirement "Pragmatically, clients MUST NOT send". I'm not sure operationally how to ensure pragmatic client behavior - maybe a "pragmatic client" profile😊 I'll save that question for my ballot comment. And of course a google of pragmatic is very entertaining:

Ow! Mike is my friend. Don't go dissing my friend!
I think the problem in communication we've just experienced is because Mike strayed away from Last Call discussion on a specific document, to asking/discussing a more general question of how IETF can better communicate with enterprises and perhaps even engage with enterprises to make it easier to operationalize protocols inside enterprise networks. I didn't see Mike suggesting any changes to the draft in Last Call, relevant to this question. ?
I'd like to suggest that maybe we could discuss this a little more on the ietf list? But not here.
I'll see what happens if I start a thread over there (ietf@xxxxxxxx) ...
