Where can I get native IPv6 / Which ISP's provide IPv6? Where can I get native IPv6 transit? Which PoP should I choose? Why are some PoP's not available for tunnels

Where can I get native IPv6 / Which ISP's provide IPv6?

The following is a list of providers who can provide native IPv6 to their customers Note that this list only comprises Access Providers and not hosting providers. Most hosting providers can provide IPv6 already simply because it is native IPv6. The list contains both consumer and business ISP's or in effect any ISP who provides access to an end-site.

Japanese IPv6 Access Providers are listed on IPv6 Style: IPv6 Services in Japan .

Russian IPv6 Access Providers are listed on version6.ru's Russian ISP List .

For Tunneled connectivity check the Tunnel Brokers list.
For Transit providers check the IPv6 Transit list.

The IPv6 Providers

TLD	Provider	Prefix	Link	Technology	Notes
	Hotze.com GmbH	2a02:5d8::/32	DSL, Ethernet	Ethernet
	Interoute	2001:1478::/32	Ethernet	Ethernet

The "Technology" column either contains:

• Ethernet: Ethernet, or in the case of DSL actually bridged from ATM
• PPPv6: existing or additional PPP session which carries IPv6

Getting Listed

When you are an ISP providing IPv6 connectivity to endsites and you are not yet listed above, then please contact SixXS, providing them with the above information.

Would it not be bad for SixXS if Native IPv6 was available everywhere?

Why would it? One of the targets of SixXS is to stop providing tunnels to endusers because everybody can get native IPv6 connectivity. Thus if there are enough providers that people don't need tunnels any more, our mission is successful.
