I agree with your comment. We had missed these.
These should be included in the document.

I agree here also.
These mixed addresses have special meanings.
Also to avoid confusion, I think it should not be converted to hex.

Regrettably, ISATAP and IPv4-translated addresses will converted
to hex in inet_ntop().
Even if we change current code, to deploy new code is not easy.
