ping6: getaddrinfo -- nodename nor servname provided, or not known

Hi all,

I disabled IPv4 function on my MacBook Pro, and then only use IPv6 function on it.

MacBook Pro got IPv6 address through RA message, and DNSv6 server address through DHCPv6 message.

DNSv6 server address is fe80::1

I try the following command in the console

ping6 ipv6.google.com

then response the following messages

ping6: getaddrinfo -- nodename nor servname provided, or not known

I can ping6 fe80::1%en0 and ping6 2001:b000::1 successfully

I don't know what's wrong...

Does somebody know how to solve it?

Many thanks
