[6bed4-devel] Have you considered stateless NAT64 to implement dual stack?

[<ebi...@xm...>]

I took a quick look and the complexity of stateless nat64 looks to
be about 1000 lines of code or about the same as your original 6bed4
tunnel that did not directly attempt to connect peer endpoints.
See http://www.litech.org/tayga/

I think with just a little care by mapping all of the v4 addresses
into the ipv4 compatible addresses aka ::ffff:0:0/96  you can use
only ipv6 addresses and apis and still talk over the ipv4 network
with no noticabley code size difference as compared to 6bed4.

This does indicate that you would need to implement ICE aka RFC5245 in
your VOIP clients but RFC5245 is required for proper IPv6 support
anyway, and the implementation if not the specification is pretty
simple.
