PHP - 使用多个IPv6地址连接远程服务器

I'm preparing to buy 1000 IPv6 addresses in my ISP provider to build a service for big data processing (calmly, I'm not a spammer :D)

My question is: how can I connect to eg. google.com using my 843th address from venet0 interface? I preffer cURL as I already wrote a HTTP class based on cURL.

Thank you for your time! Have a nice day.

Have you tried setting CURLOPT_INTERFACE?

The name of the outgoing network interface to use. This can be an interface name, an IP address or a host name
