Comparison of IPv6 support by major transit providers

Internet Protocol Version 6 (IPv6) is not yet universally available as of 2011, but support by major ISPs and transit providers is steadily increasing. Many major transit providers offer an IPv6 service to their customers, but do not have a ubiquitous view of all other IPv6 networks. Other aspects of this service vary widely from one major ISP to the next.
