    "abstract": "Many end-user sites in the Internet today still have predominantly IPv4 internal infrastructures. These sites range in size from small home/office networks to large corporate enterprise networks, but share the commonality that IPv4 provides satisfactory internal routing and addressing services for most applications. As more and more IPv6-only services are deployed, however, end-user devices within such sites will increasingly require at least basic IPv6 functionality. This document therefore provides operational guidance for deployment of IPv6 within predominantly IPv4 sites using the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP).",
