Found while reviewing #2700 and confirmed by a Sonnet cross-review. Identical on main. Two MH mobility options raise a plain ValueError, not a pcapkit BaseError, when parsed on their own:

  • Option 6 (MNP): a prefix with host bits set raises "has host bits set", from IPv6Network.
  • Option 27 (Timestamp): a time past year 9999 raises "year is out of range", from datetime.

Inside IPv6 both stay Raw and rebuild exactly. Standalone they should raise ProtocolError, or keep the value in a form the data model can hold, so that the round trip still matches.
