I have one quick question for my own understanding:

So, the security of this approach relies on how securely the client
can get the resolver's address, e.g.,
- Using SEND for RAs with RFC 6106
- (If and when it's defined) Using public-key based DHCPv6
  authentication
And, to make this part secure, the client needs to get the router's
certification or the server's public key securely beforehand.

Is my understanding correct?
