IPv6 addresses have three types:

 

Global Unicast Address –Scope Internet- routed on Internet

Unique Local — Scope Internal Network or VPN internally routable, but Not routed on Internet

Link Local – Scope network link- Not Routed internally or externally.

 

Global and Public Addresses

Global addresses are routable on the internet and start with 2001:

 

Internal Addresses- Link Local and Unique Local

These addresses are not routed on the Internet and are reserved for internal networks.

 

IPv6  has two Internal address types.

Link Local
Unique Local

 

Link Local

 

These are meant to be used inside an internal network, and again they are not routed on the Internet.

 

Link local addresses start with fe80

 

They are restricted to a link and are not routed on the Internal network or the Internet.

 

Link Local addresses are self assigned i.e. they do not require a DHCP server.

 

A link local address is required on every IP6 interface even if no routing is present.

 

Unique Local

Unique Local are meant to be used inside an internal network.

 

They are routed on the Internal network but not routed on the Internet.

The address space is divided into two /8 spaces: fc00::/8 for globally assigned addressing, and fd00::/8 for locally assigned addressing.

 

For manually assignment by an organisation use the fd00 prefix.
