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.

Learning Roadmaps

IPv6 Learning Roadmap

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.

Technical Reference

TCP/IP Technical Reference

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.
