3. IPv6 Address Space
128 bits expressed in eight groups of 4 hexidecimal characters
Example address:
2001:0db8:0000:0000:0000:0000:1428:57ab

4. Notation Variations
If one or more four-digit group(s) is 0000, the zeros may be omitted and replaced with two colons(::). Following this rule, any number of consecutive 0000 groups may be reduced to two colons, as long as there is only one double colon used in an address.
Example-
2001:0db8:0000:0000:0000:0000:1428:57ab :0db8::1428:57ab

5. Notation Variations
It is also acceptable to just replace a string of 4 zeroes with a single zero
Example-
2001:0db8:0000:0000:0000:0000:1428:57ab
2001:0db8:0:0:0:0:1428:57ab

6. Address Types No broadcast! Loopback - ::1
Multicast – starts with
Anycast – one to nearest
Link local (fe8 to feb) – similar to AIPA
Unique local – similar to , ,
Global unicast

7. Configuring a Host Stateless address autoconfiguration
IPv6 hosts can be configured to automatically send an ICMPv6 router discovery message when they first connect to a network. This message is called a link-local multicast router solicitation request. If configured suitably, routers respond to such a request with a router advertisement packet that contains the network address and other network-layer configuration parameters.
Stateless autoconfiguration is only suitable for hosts: routers must be configured manually or by other means.

8. Configuring a Host Stateful Configuration (DHCP)
If IPv6 autoconfiguration is not suitable, a host can use stateful configuration (DHCPv6)
A host can be configured manually.
Type in entire address
EUI-64 Interface ID
Configure prefix only; MAC address plus 16 bits used for host portion.
