IPv6 addresses are plentiful, so a proxy service can give you fresh ones at a small fraction of the IPv4 price. For sites that answer over IPv6, the result is the same page for much less money.
Before buying, check the target. A site with an AAAA record in its DNS answers over IPv6; a site without one cannot be opened through an IPv6 proxy at all. PiratProxies sells IPv6 datacenter and IPv6 residential plans, both with country targeting.
