Welcome to the AFTR Development Site

ISC AFTR is an implementation of an IPv4/IPv6 transition protocol based on  Dual-Stack Lite, which is under development by several large ISPs within the IETF protocol standards development process.

Dual-Stack Lite is one of a family of technologies intended to ease the transition from IPv4 to IPv6 by allowing legacy IPv4 applications to interact with IPv4 content providers and services over an IPv6 carrier infrastructure. This allows ISPs to share increasingly-scarce IPv4 addresses among multiple customers, while simultaneously enabling IPv6-capable devices, applications, and services to start using native IPv6.

ISC AFTR consists of the code for an AFTR element (IPv6 tunnel concentrator and large-scale NAT) and instructions for building a B4 element (tunnel initiator) on a Linksys home gateway.
