You have 2002:47b1:11ab::/48. If your ISP supports it, packets sent to that /48 will be delivered to you as native v6 packets, otherwise they'll be stuffed into a v4 packet which will be sent to 71.177.17.171. Or there's ::ffff:71.177.17.171 which will reach you using unmodified v4 packets.
That's two different ways your v4 address is present in v6.
(On home Internet you'll probably need your ISP to handle the announcements, like they already do for your v4 address.)
