 An endpoint MAY send data to an unvalidated peer address, but it MUST protect
 against potential attacks as described in {{address-spoofing}} and

 An endpoint only changes the address that it sends packets to in response to the
 highest-numbered non-probing packet. This ensures that an endpoint does not send
