-------
I have concern:

3. DHCPv6 Encapsulating Options

"There is no order
implied by the order of options sent or received. It is up to the
receiving client to determine which order to use the DNS server
configurations."

Let's not wait for some non-standard way to decide the order. Please add
'priority' (and possibly 'weight') fields to the "OPTION_DNS_TLS" now, like
in MX and SRV records.

-------
And a question:

Appendix A. ISC DHCPv6 Configuration Example

"option tls.adn code 228 = domain-list;

option tls.adn "dns.quad9.net";"

Why is this defined as a list, but only a single domain is configured. And
the text (in 1. Introduction) indicates only one domain is allowed per
option. Is there a single domain format that should be used?
