Thanks Erik, Indeed, I have added a paragraph to the Security Considerations that preventing tracking of the public IP of a routing device that performs NAT is beyond the scope of this document, see: https://github.com/NLnetLabs/draft-sury-toorop-dns-cookies-algorithms/pull/23/commits/83155e4bfed1afb08611723a13f9ebc045179e63 The nits have been processed too.
