forward相关域名到2001:470:20::2即可

$ dig @2001:470:20::2 docs.google.com AAAA

; <<>> DiG 9.7.1 <<>> @2001:470:20::2 docs.google.com AAAA
; (1 server found)

V2EX DNS 目前已经支持 IPV6 解析的。

$ dig @dns.v2ex.com docs.google.com AAAA

docs.google.com IN CNAME writely.l.google.com

$ dig @dns.v2ex.com writely.l.google.com AAAA

另外forward到tserv20.hkg1.ipv6.he.net可能更好，返回的地址是google在香港的服务器

$ dig @tserv20.hkg1.ipv6.he.net www.google.com AAAA
