In what way is it backwards compatible? It's not as if all allocations are kept and people just add 96 bits to their existing addresses. They are completely disjoint address spaces and protocols, as compatible as Tor is with the general internet: to communicate between the two, you need a proxy.

I was wrong. I must have rememberd an early draft or the translation layer

[mulmen]

Tor operates over the Internet.

Did you mean to compare Tor to the World Wide Web?

[eznzt]

Tor is sort of a virtual network. You need a gateway between the virtual network and the Internet to access the Internet.

[mulmen]

Tor overlays the Internet. It can’t operate without that underlying network. That is not how IPv6 works relative to IPv4.

[lucb1e]

Yeah, that is indeed a flaw in the comparison.

[Dylan16807]

So I'm not saying it's backwards compatible, exactly, but what would you call 64:ff9b::?

[mulmen]

A reserved gateway address space?

[Dylan16807]

By embedding the IPv4 address space inside the IPv6 address space.

They are different protocols but they are not disjoint address spaces.

You add 96 bits to the address and boom it's converted.
