Yes and No,

By default when using NetworkManager, the default is to use IPv6 (it set to Auto). But if you network don't have a IPv6 DHCP or some sort of IPv6 DHCP forwarder, you won't get any Public route able IPv6 address. IPv6 address which start with FE80* are called Link-local unicast and are used only with you computer ( https://tools.ietf.org/html/rfc3513#s... ).
