Teredo IPv6 Private IPv4 Connectivity If the ISP provides only private IPv4 addresses, as described in RFC 1918, then IPv6 connectivity is not expected to be enabled directly by home routers. Instead, individual hosts will acquire IPv6 addresses and connectivity themselves by using Teredo technology, transparently to the home routers. Teredo is an IPv6 transition technology that tunnels IPv6 packets as IPv4-based User Datagram Protocol (UDP) messages using UDP port 3544.
