The structure of Teredo IPv6 addressing is as follows:
i. First 32 bits, that is 0 to 31, are set to the Teredo prefix (normally 2001:0000::/32).
ii. Bits 32 to 63 embed the primary IPv4 address of the Teredo server being used.
iii. Bits 64 to 79 can be used to.define flags.
iv. Bits 80 to 95 contain the obfuscated UDP port number, which is mapped by the NAT devices to the Teredo client with all the bits inverted.
v. Bits 96 to 127 contain the obfuscated IPv4 address. This is the public IPv4 address of the NAT devices with all the bits inverted.
