Hi Jaques, et al.

Tom Pusateri can probably say something on his now expired
https://www.ietf.org/archive/id/draft-pusateri-dhc-dns-driu-00.txt.  

The git commentary at
https://github.com/pusateri/draft-tpwt-dhc-dns-discovery says:
    Ted Lemon made a good argument that DHCP should only be used for
boostrapping initial network 
    parameters and not for full fledged configuration of all network
parameters.

    There was enough consensus that we feel that moving forward with this
work would go against the 
    wishes of the IETF community.

    There still is a need for configuring the ADN in a campus environment
where all of the servers are 
    controlled by the network administrator but a different proposal will
need to be invented. 

I wonder if ALL (including the original) DNS discovery options) fall into
that area or not, and if that 
possibly changed over time, but likely there was a debate that already
explored the topic in dhc

BR, 

Normen

Betreff: Re: [DNSOP] [Doh] New I-D: draft-reid-doh-operator

In article <428d5ff2b5704cdf956a5919e330e4dc@cira.ca>; you write:
>Plus! 
>Is anyone looking at adding DoH and DoT servers as part of DHCP/SLAAC?

I believe that for DoT, the idea is that the client just probes the DNS
server address on port 853 and uses it if it gets an answer.  I suppose you
could try the same thing on port 443 but that seems riskier.

R's,
John
