global unicast address or GUA

http://www.tcpipguide.com/free/t_IPv6GlobalUnicastAddressFormat-2.htm

The part of the IPv6 address space set aside for unicast addresses is structured into an address format that uses the first 48 bits for the routing prefix (like a network ID), the next 16 bits for a subnet ID, and the final 64 bits for an interface ID (like a host ID).
