Hi Gabbi, this is a long standing issue already on trac, the mailing list and bug tracker entry bellow is probably more relevant to this. Gabbi Fisher:

I wanted to see if there are any plans to add Tor exit nodes with IPv6 addresses to https://check.torproject.org/exit-addresses. I've observed some while using Tor, but do not see them on this list.
