1, IPv6 Introduction
The IPV6 address is 128 bits long and addresses a total of 2^128.
IPV6 address format: x:x:x:x:x:x:x:x, where x is 16 binary.
IPV6 Simplification:
2001:0DB8:010F:0001:0000:0000:0000:0D0C Remove leading 0
2001:db8:10f:1:0:0:0:d0c continuous multiple 0 can be used:: Replace
2001:db8:10f:1:: d0c
2001:0db8:0000:0000:ffff:0000:0000:0d0c
can be expressed as
2001:DB8::FFFF:0:0:0D0C or 2001:0db8:0:00:ffff::0d0c
But cannot be expressed as
2001:0db8::ffff::0d0c
Because this does not know before and after two:: how many 0
Example:
Ff02:0:0:0:0:0:0:1Ff02::1
ff15:0:0:0:0:0:1:c001ff15::1:c001
0:0:0:0:0:0:0:1:: 1
0:0:0:0:0:0:0:0::

IPV6 Address Categories
Unicast unicast (single-to-one)
Aggregate Global Unicast Addresses (public network)2000::/3
Link-local AddressesFE80::/10
Site-local Addresses (private network)FEC0::/10
Unspecified::/128
Loopback:: 1/128
IPV4 compatible directly converts the 10 binary into 16 binary
Multicast multicast (one-to-many) ff00::/8
Anycast anycast (pair of most recent)
EUI-64 (assuming MAC address is 00:90:27:17:fc:0f)
Step one: Divide the MAC address in half and insert Fffe in the middle
00:90:27:ff:fe:17:fc:0f
Part Two: Swap the seventh bit 0, 1 of the first byte
00000000:90:27:ff:fe:17:fc:0f
00000010:90:27:ff:fe:17:fc:0f
02::90:27:ff:fe:17:fc:0f
Solicited-node multicast addressff02::1:xx:xxxx back 24 bits for IPV6 unicast addresses after 24 bits
Each IPV6 unicast address corresponds to a solicited-node multicast address
The next hop for the route is Link-local Addresses.
