All I am saying is this:
,--------. ,---. ,------.
|Endpoint| |CPE| |ISPDNS|
`---+----' `-+-' `--+---'
| 1 A/AAAA Query |
| --------------------------------->
| | |
| 2 Response(A/AAAA) |
| <---------------------------------
| | |
| |3 add ACL/TR.369|
| | or similar |
| |<----------------
,---+----. ,-+-. ,--+---.
|Endpoint| |CPE| |ISPDNS|
`--------' `---' `------'
You can substitute “ISPDNS” for whoever offers the CPE (like Google/Eero/etc,
so long as the DNS infra and CPE know about one another and agree on a control
channel).
