Understanding IP Version 6 (IPv6)
This topic gives an overview of IP version 6 (IPv6), including its uses and benefits.
The ongoing expansive growth of the Internet and the need to provide IP addresses to accommodate it—to support increasing numbers of new users, computer networks, Internet-enabled devices, and new and improved applications for collaboration and communication—is escalating the emergent use of a new IP protocol. IPv6, with its robust architecture, was designed to satisfy these current and anticipated near future requirements.
IP version 4 (IPv4) is widely used throughout the world today for the Internet, intranets, and private networks. IPv6 builds upon the functionality and structure of IPv4 in the following ways:
- Provides a simplified and enhanced packet header to allow for more efficient routing.
- Improves support for mobile phones and other mobile computing devices.
- Enforces increased, mandatory data security through IPsec (which was originally designed for it).
- Provides more extensive quality-of-service (QoS) support.
