It took a while, but I finally got native IPv6 at home from Ziggo, my cable ISP a few months ago. All it took was a new cable modem / home router, because they don't support IPv6 on the one I've had since I signed up with them six years ago. And lo and behold: I got myself some IPv6:
$ ifconfig en0
en0: flags=8863 mtu 1500
ether xx:xx:xx:xx:xx:xx
inet6 fe80::8d:5a:e4d:176f%en0 prefixlen 64 secured scopeid 0x8
inet 192.168.78.24 netmask 0xffffff00 broadcast 192.168.78.255
inet6 2001:1c00:d00:7300:xxxx:xxxx:xxxx:xxxx prefixlen 64 autoconf secured
inet6 2001:1c00:d00:7300:75bf:1d31:ac76:d080 prefixlen 64 autoconf temporary
nd6 options=201
media: autoselect
