Comparison of IPv6 support by major transit providers
Internet Protocol Version 6 (IPv6) is not yet universally available as of 2012, 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.

Notes
- ↑ Number of routes advertised to customers
- ↑ Number of routes advertised over non-customer BGP peering sessions
- ↑ Some networks do not have global reach-ability to some other major networks.
- ↑ This data changes frequently as IPv6 adoption progresses.
- ↑ Number of unique IPv6 routes (/48 or shorter) visible on route-views6.routeviews.org MRT, for comparison to transit networks
- ↑ As of 2010-JUL-24, in certain regions Cogent charges a $50 per month fee to configure IPv6 for their customers.
- ↑ Savvis has advised their customers that their backbone is IPv6 capable since 2009. However, they do not have an offering for transit service to customers and to look for offerings in 2012. In addition, Savvis managed hosting and cloud services do not support IPv6, with NO roadmap or release plans announced. (February 2011)
- ↑ Sprint has ceased implementing new tunnels on their test network and will begin removing them on January 31, 2011 in favor of dual-stack on AS1239.
