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.
