Transmission Control Protocol/Internet Protocol (TCP/IP) is an industry standard suite of protocols that is designed for large networks consisting of network segments that are connected by routers. TCP/IP is the core protocol suite that is used on the Internet.

Many TCP/IP application protocols were designed to access and transfer data between dissimilar systems. These protocols include HTTP, FTP, and Telnet. TCP/IP components in Windows allow standards-based connectivity to other operating system platforms.

Microsoft Windows Server 2008 R2, Windows 7, Windows Server 2008, and Windows Vista include a complete redesign of the TCP/IP protocol suite. The TCP/IP redesign supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) to meet the connectivity and performance requirements of today's networked environments.

The IPv6 Learning Roadmap can help you build your understanding of IPv6. It includes prerequisite topics that cover a variety of networking and infrastructure fundamentals and resources that help you learn introductory, intermediate, and advanced technical details about IPv6.

The TCP/IP (v4 and v6) Technical Reference describes how TCP/IP with IPv4 and IPv6 relates to other networking protocols, the functions it performs, how IP addresses are structured and assigned, and how packets are structured and routed.
