did update late,

* Hoffman, DNS over HTTP BoF Happening
Location: Studio 7 at 18:45
Http people want exact format of DNS HTTP, as http people want to
have the ability to push DNS messages over HTTP.
there are multiple drafts in this space.

Multiple responses will be discussed on mailing list.

* Chairs, [draft-ietf-dnsop-no-response-issue]
(https://datatracker.ietf.org/doc/draft-ietf-dnsop-no-response-issue/), 5 min
    - Action:  With rewritten redmediation, ready for WGLC?


## Current Working Group Business

13:50
* Cheshire, [draft-ietf-dnsop-session-signal]
(https://datatracker.ietf.org/doc/draft-ietf-dnsop-session-signal/), 5 min

Question 1: Ray Bellis advocates using abbreviated 4-byte header instead of
traditional 12-byte header.
Is this a good idea?
Some opinions on either side:
Wes Hardaker asks if the savings are worth the security of risk creating a
new parsing engine?
Ray Bellis says this is doable
SC does not care strongly about optimizations. Is asking for the opinion
of the group.

Question 2: Does every message need a response? Or can there be unilateral
one-way messages?

Question 3: Proposed terminology change, for clarity, from “idle timeout”
to “KeepAlive interval”?

## New Working Group Business

* Cheshire, [draft-cheshire-sudn-ipv4only-dot-arpa]
(https://datatracker.ietf.org/doc/draft-cheshire-sudn-ipv4only-dot-arpa/), 5 min
This is special name, but it is not listed in the Special Names registry.
Usage is quite common on IPv6-only networks like cellphone operators have.
Andrew Sullivan: There was fight in the WG that defined this (behave) over
this topic, thus DNSOP should not adopt.
Making the TTLS longer will mitigate the effect of server outages.
Dan York: why do we think client will stop using this?
SC: We don't think clients will stop using this. They will continue to use
it, and we want it to work reliably.
Paul Hoffman: Put it in the registry
SC: Because the name is not listed as a special name, DNS64 gateways have
to do a pointless lookup
(that they already know the answer to) and that pointless lookup affects
performance and reliability.
Peter Koch: This is not needed and you may do more harm
Matt Pounsett: This is special name and the document should be published
Andrew Sullivan: On first reading of this draft I was convinced by the
points it makes.
Now I’m starting to have second thoughts again.
I encourage others to read the document and form their own opinions.

* Bortzmeyer, [draft-wallstrom-dnsop-dns-delegation-requirements]
(https://datatracker.ietf.org/doc/draft-wallstrom-dnsop-dns-delegation-requirements/), 10 min
    - Action:  Worth adopting?

    Jim Reed: what kind of status ==> BCP
    discussion about Public Suffix list
    George M: He strugles with delegation tests after delegations;
    policing goes to bad place
    Olafur: against adoption without major changes
    John L: scared
    Peter Koch: does post delegation checks hard to create list that
    everyone can agree on; not describing eough may decrease the value
    of the document, wants list of pure requirements
    SW: non-response draft has been tuned down and how has tracktion
    Ed Lewis: IETF should define the requirements for healthy delegations
     not talk about how to/if enforce
    David Conrad: agrees with Ed but invovkes policy
    Jim Reid: agrees with Peter Koch for recommendations
    Paul Hoffman: about TLS testing, there are multiple testers and they
    all use differnt criteria's, the document is sloppy; Agrues against
    restricting to hostnames.
       "If you want delegation tests here is a list"
    OndrejS: Things will be moving targets,
    SW: will take question of the adoption is going to be taken to the list.

* Dickinson, [draft-dickinson-dnsop-dns-capture-format]
(https://datatracker.ietf.org/doc/draft-dickinson-dnsop-dns-capture-format/), 10 min
    - Action: More work on formats?
    - IPR Issue

  -- IPR disclosure WO
     Shane Kerr: should adopt; performance?
       SD: yes they have performance results, "remving data" seems to
       help compression
     GeorgeM: Defintily adopt this is appropritate. Observations: compression
     of pcap is quite good.
       SD: needs more meta data
     SW: wg has not position on the IPR
     Kaveh: Supports adoption strongly
     Wes H: +1 on adoption

     Hum for adotpion:  strong for ; none against


14:53
* Fujiwara, [draft-fujiwara-dnsop-resolver-update]
(https://datatracker.ietf.org/doc/draft-fujiwara-dnsop-resolver-update/), 15 min
    - Action: Continue with work?

  Olafur: strongly disagree there are no need for these changes
  Onderj:  He supports making the behavior more deterministic
  Witold:   This is a ugly hack, do not proceed
  Ed Lews: NS will differ; wants
  Peter Koch: small change to make sure delegation data is purged regularly
  MarkA: only cache NS longer than the parent TTL even if they are
  updated by shorter TTL in child

  SW: more discussion needed before adoption

(https://datatracker.ietf.org/doc/draft-yao-dnsop-accompanying-questions/), 5 min
    - Action: Requested adoption, is the draft and the WG ready?

    considerations

(https://tools.ietf.org/html/draft-muks-dnsop-dns-catalog-zones-01), 5 min
