Introduction to IPv6 transition technology-Teredo

Teredo is an Address Allocation and automatic tunneling technology. It is a type of IPv6 transition technology that can achieve IPv6 unicast connections across the IPv4 Internet. Before that, an automatic tunnel technology that can implement IPv6 unicast connections through the IPv4 Internet-6to4. The 6to4 vro uses a public IPv4 address to build the 6to4 prefix. This serves as an IPv6 announcement and promotes the vro. The 6to4 router compresses and decompress the IPv6 data stream passing through the site node.

The 6to4 technology relies on the configuration of Public IPv4 addresses and the 6to4 routing function used in the border device. In many small office/Home Office SOHO configurations, IPv4 Internet address translation (NAT) is widely used. To learn more
