Use cURL with an IPv6 IP-check service to confirm that your SOCKS5 IPv6 proxy is working.

Replace the placeholders with the details shown in your Proxy-Cheap dashboard:

curl -v -x socks5h://USERNAME:PASSWORD@HOST:PORT https://api64.ipify.org

A successful request should return an IPv6 address.

Use socks5h when connecting to a domain name. With socks5h, DNS resolution happens through the proxy rather than on your local device.

If the request fails, check the hostname, port, username, password, and proxy protocol. Also confirm that the destination website supports IPv6, as an IPv6-only proxy cannot reach an IPv4-only destination.
