IPv6 Addressing and Basic Connectivity

The switch supports only IPv6 unicast addresses. It does not support site-local unicast addresses or
multicast addresses.
The IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal fields separated by
colons in the format: n:n:n:n:n:n:n:n. it is an example of an IPv6 address:
The leading zeros in each field are optional, implementation is easier without them. it is the same address
without leading zeros:
You can also use two colons (::) to represent successive hexadecimal fields of zeros, but you can use this
short version only once in each address:
