It might be worth calling out that if a DTLS server sends HelloVerifyRequest (as it normally will on the open Internet), there’s no need to tear down the DTLS association.

Agreed. Added the following line:
If TURN over DTLS server has been configured to require a cookie exchange and if HelloVerifyRequest is received from the TURN servers on both
IP addresses families then the client can silently abandon the connection on the IP address family with lower precedence.

Other than that, this section looks good.

Thanks for the review.
