Python pycurl 如何访问ipv6 网站

Supports IPv6!
If compiled with IPv6 support enabled, All protocols work splendidly on IPv6 stacks. There are some minor quirks to keep in mind: kerberos4 does not work over IPv6 by design and the SOCKS4 support is not properly adapted for IPv6.
There is nothing in particular needed to get IPv6 to be used, the library API remains exactly the same and adjusts to IPv4/Ipv6 dynamicly. You can use host names that only have AAAA DNS records, or you can use IPv6 IP-only style addresses like [::1].
