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,
