2.6.8 IPv6 Command
Brief Introduction to IPv6 Addressing
IPv6 addresses are 128 bits long and number about 3.4×1038. IPv6 addresses are written in eight
groups of four hexadecimal digits separated by colons, such as
2001:0db8:85a3:0000:0000:8a2e:0370:7334
IPv6 unicast addresses other than those that start with binary 000 are logically divided into two
parts: a 64-bit network prefix and a 64-bit interface identifier.
Stateless Autoconfiguration
IPv6 lets any host generate its own IP address and check if it's unique in the scope where it will be
used. IPv6 addresses consist of two parts. The leftmost 64 bits are the subnet prefix to which the
host is connected, and the rightmost 64 bits are the identifier of the host's interface on the subnet.
This means that the identifier need only be unique on the subnet to which the host is connected,
which makes it much easier for the host to check for uniqueness on its own.
