Administrator Guide

For example, 2001:0db8:1234::/48 stands for the network with addresses 2001:0db8:1234:0000:0000:0000:0000:0000 through
2001:0db8:1234:ffff:ffff:ffff:ffff:ffff.
Link-local Addresses
Link-local addresses, starting with fe80:, are assigned only in the local link area.
The addresses are generated usually automatically by the operating system's IP layer for each network interface. This provides instant
automatic network connectivity for any IPv6 host and means that if several hosts connect to a common hub or switch, they have an
instant communication path via their link-local IPv6 address.
Link-local addresses cannot be routed to the public Internet.
Static and Dynamic Addressing
Static IPv6 addresses are manually assigned to a computer by an administrator.
Dynamic IPv6 addresses are assigned either randomly or by a server using dynamic host configuration protocol (DHCP). Even though IPv6
addresses assigned using DHCP may stay the same for long periods of time, they can change. In some cases, a network administrator may
implement dynamically assigned static IPv6 addresses. In this case, a DHCP server is used, but it is specifically configured to always assign
the same IPv6 address to a particular computer, and never to assign that IP address to another computer. This allows static IPv6
addresses to be configured in one place, without having to specifically configure each computer on the network in a different way.
In IPv6, every interface, whether using static or dynamic address assignments, also receives a local-link address automatically in the
fe80::/64 subnet.
Implementing IPv6 with Dell EMC Networking OS
Dell EMC Networking OS supports both IPv4 and IPv6 and both may be used simultaneously in your system.
The following table lists the Dell EMC Networking OS version in which an IPv6 feature became available for each platform. The sections
following the table give greater detail about the feature.
