assuming by ping6 2001:0db8:200:f101::1 you mean ping6 to a real IPv6 address rather than the 2001:db8::/32 demonstration address, then yes, you probably have a link local IPv6 address only. You can also check by running ifconfig (or the similar utility for your OS) and looking for a globally routable IPv6 addresses on your network interface. If you only have addresses starting with fe80 then you are likely link local only and not getting anything globally routable from your ISP.
