My AT&T cellphone (via MVNO Tracfone) has a 10/8 IPv4 address and IPv6
address 2600:380:28be:8b34:2504:2096:6ac7:6262.  But when I connect to a
web site that reports the connecting address, it says I'm
2600:387:a:9a2::8.

What's going on there?  Those are both within at&t's 2600:300::/24', but
am I behind a NAT66?  An aggressive web cache?
