A: Yes and no. Our core network (AS1257) is fully IPv6 enabled and has been so since mid-2008. We have actively been peering since late 2008 and reach most of the IPv6 Internet over the same paths we reach it for IPv4. We are currently working on enabling IPv6 connectivity the last mile so our customers can enjoy the simple life brought by IPv6.
A: That depends. Please review the cases listed on this page and find the entry matching your conditions.
A: Tele2 does not, at this time (late 2010), offer native IPv6 to any residential customers in any country. You can however use tunneling techniques such as Teredo or 6to4 to reach the IPv6 Internet. See 6to4 and Teredo
A:It is most likely available for your circuit in case you are a international customer of Tele2. If the BGP router you are receiving your table from is part of AS1257, you are probably a customer of Tele2 International Wholesale. In cases where it is not possible, we offer tunneled services up to Gigabit speeds. Please consult your account manager.
A:In Windows 7, there is a Teredo client integrated in the operating system. Depending on your installation, it could be enabled by default, otherwise it will need to be enabled.
Windows XP does not by default include Teredo, but it can be easily installed and enabled by two commands:
netsh interface ipv6 install
netsh interface ipv6 set teredo client
On Ubuntu, other Linux distros or other similar Unix-like systems, there is a Teredo client called Miredo, please see it's homepage for installation documentation.
