Thanks. This returns the provider server ip (dns?)
It returns the specific destination IP address libcurl used to perform the transfer.
and local_ip the reserved ip to communicate with my modem.
IP packets only have two IP addresses. The source and the destination. libcurl can return both for you.
No other options to show the same as for ex. http://mybrowserinfo.com/?
If the local address is different in a remote place compared to what it is when libcurl sends out packets, then something has changed that address along the way. A so called Network Address Trnaslator, or NAT for short. libcurl has no knowledge of that and it can't tell you info from that translation since it never sees that other address, only the remote server does.
