Internet protocol version 6 (IPv6) routing is the successor to IPv4. Due to the rapid growth in internet users and IP addresses,

IPv4 is reaching its maximum usage. IPv6 will eventually replace IPv4 usage to allow for the constant expansion.

This chapter provides a brief description of the differences between IPv4 and IPv6, and the Dell Networking support of IPv6.

This chapter is not intended to be a comprehensive description of IPv6.

The IPv6 basic commands are supported on all platforms. However, not all features are supported on all platforms,

nor for all releases. To determine the Dell Networking Operating System (OS) version supporting which features and

platforms, refer to

Implementing IPv6 with Dell Networking

Even though Dell Networking OS listens to all ports, you can only use the ports starting from 1024 for IPv6 traffic.

Ports from 0 to 1023 are reserved for internal use and you cannot use them for IPv6 traffic.

Protocol Overview

IPv6 is an evolution of IPv4. IPv6 is generally installed as an upgrade in devices and operating systems. Most new devices and

operating systems support both IPv4 and IPv6.

Some key changes in IPv6 are:

Extended address space

Stateless autoconfiguration

Header format simplification

Improved support for options and extensions
