💡 怎么办 / What to do
   17NAS 收到本次请求时使用的是 IPv4。
   这只代表本次请求路径，不代表设备一定没有 IPv6。
   如需另行验证不经过环境代理的直连 IPv6，可运行：curl --connect-timeout 5 --max-time 10 --noproxy '*' -6 https://v6.17nas.com
   17NAS received this request over IPv4.
   This only describes this request path; it does not prove that the device has no IPv6.
   To separately test direct IPv6 without environment proxies, run: curl --connect-timeout 5 --max-time 10 --noproxy '*' -6 https://v6.17nas.com
