RFC 2374

This document defines an IPv6 aggregatable global unicast address
   format for use in the Internet.  The address format defined in this
   document is consistent with the IPv6 Protocol [IPV6] and the "IPv6
   Addressing Architecture" [ARCH].  It is designed to facilitate
   scalable Internet routing.

A global unicast address is the IPv6 equivalent of an IPv4 public unicast address, and it typically starts with a 2. A link-local IPv6 address is equivalent to an IPv4 APIPA address and it starts with fe8. A site-local IPv6 address is equivalent to an IPv4 private address and it starts with fec0. The special IPv6 addresses :: and ::1 are equivalent to the IPv4 addresses 0.0.0.0 and 127.0.0.1. Multicast IPv6 addresses start with ff. Anycast addresses are assigned only to routers and are beyond the scope of the 70-680 examination.
