Do I need Teredo if I have IPv6?

Teredo is a temporary measure. In the long term, all IPv6 hosts should use native IPv6 connectivity. Teredo should be disabled when native IPv6 connectivity becomes available. Christian Huitema developed Teredo at Microsoft, and the IETF standardized it as RFC 4380.

Do I want to enable IPv6?

IPv6 is extremely important for the long-term health of the Internet. Switching from IPv4 to IPv6 will give the Internet a much larger pool of IP addresses. It should also allow every device to have its own public IP address, rather than be hidden behind a NAT router.

Why am I getting an IPv6 address?

What is Teredo in my router?

Which is the correct prefix for a Teredo address?

A Teredo address consists of the following: The first 32 bits are for the Teredo prefix, which is the same for all Teredo addresses. Windows XP and Windows Server 2003 initially used the 3FFE:831F::/32 Teredo prefix. The prefix defined for Teredo in RFC 4380 is 2001::/32 and is the prefix used by Teredo in Windows Vista and Windows Server 2008.

How are Teredo clients assigned public IPv6 addresses?

A computer with a host-specific relay uses Teredo to communicate with Teredo clients, but sticks to its main IPv6 connectivity provider to reach the rest of the IPv6 Internet. Each Teredo client is assigned a public IPv6 address, which is constructed as follows (the higher order bit is numbered 0):

What are the 16 bits of Teredo address?

The 16 bits within the Flags field for Windows Vista and Windows Server 2008-based Teredo clients consists of the following: CRAAAAUG AAAAAAAA. The C bit is for the Cone flag. The R bit is reserved for future use. The U bit is for the Universal/Local flag (set to 0).

Where are the Teredo relays located on the network?

Teredo routes these datagrams on the IPv4 Internet and through NAT devices. Teredo nodes elsewhere on the IPv6 network (called Teredo relays) receive the packets, un-encapsulate them, and pass them on. Teredo is a temporary measure. In the long term, all IPv6 hosts should use native IPv6 connectivity.
