If you connect to the IRC server using IPv6, the ident request will be over IPv6 ... otherwise how would it know where to send the ident request?
Well yes, I kinda figured that. What I'm trying to figure out is how it's routed (or right now, not routed).
Computer A IPv6 -> IPv4-to-IPv6 Tunnel on Computer A -> router IPv6 -> IPv6 IRC Node
So is it...
IPv6 IRC Node Ident Request -> router IPv6 NEW
IPv6 IRC Node Ident Request -> router IPv6 ESTABLISHED -> Computer A IPv6
IPv6 IRC Node Ident Request -> router IPv6 ESTABLISHED -> Computer A IPv6-to-IPv4
If it's the first as a NEW request then I just need to figure out how to enable / compile IPv6 into widentd (which is on the *router*).
Edit: Tried to make it a little easier to understand.
