IPv6 and IIS 6.0
Internet Information Services (IIS) 6.0 provides Internet services to clients connecting over the next generation of Internet Protocol (IP) — known as IP version 6 (IPv6). When you use IPv6 with IIS on a server running the Microsoft® Windows® Server 2003 operating system, your sites can respond to both IPv6 requests and Internet Protocol version 4 (IPv4) requests. Although current demand for IPv6 is limited, the adoption of new Internet-connected devices, such as phones and handheld computers, is expected to quickly exhaust the remaining IPv4 address space and speed the transition to IPv6.
