NATless IPv6/IPv4 Address Translation | Keerti Lakshminarayan and Alok Tiagi

We will demonstrate a performant and novel approach to performing NAT, that uses a unique transition mechanism utilizing a new flag introduced to the seccomp() system call, to intercept egress connect calls to opportunistically use a transition IPv4 address when possible, saving applications the pain of dealing with the end host not being reachable, while still living in an IPv6-only environment.
