香港云服务器
共享 IPv4 + 原生 IPv6 Hong Kong VPS
Shared IPv4 + native IPv6

每台自带一个共享公网 IPv4（NAT）：出站直接走共享 IP（拉 GitHub、调用只有 IPv4 的 API 都可达，默认封出站 25）；入站只映射 SSH —— 登录地址 = 共享IP : 专属端口（开通邮件和控制台会给出），不提供其它入站端口，不是独立 IPv4、不能对外开放任意端口。同时每台独享 /64 原生 IPv6，进出无阻、原生直连。Every server includes a shared public IPv4 (NAT): outbound goes straight through the shared IP (pull GitHub, call IPv4-only APIs; port 25 blocked); inbound is limited to mapped SSH — you log in at shared-IP : your port (shown in the welcome email and console). It is not a dedicated IPv4 and you cannot open arbitrary inbound ports. Each server also gets a dedicated native /64 IPv6, in and out, direct.

2404:3881::/32 在 APNIC 登记为香港，由我们的 AS133033 在香港宣告。主流 IP 数据库大多已显示香港，个别数据库仍在更新中。2404:3881::/32 is registered with APNIC as Hong Kong and announced by our AS133033 in Hong Kong. Most major IP databases already show Hong Kong; a few are still updating.

不能直接对外开放网站（共享 IPv4 的入站只映射 SSH，不开放网站端口）。常见做法是在网站前加一层支持 IPv6 回源的 CDN（例如 Cloudflare 代理模式），IPv4 访客经 CDN 即可访问。Not for direct inbound web hosting (the shared IPv4 only maps SSH inbound, not website ports). Put an IPv6-capable CDN in front (for example Cloudflare in proxied mode) and IPv4 visitors reach you through it.

付款成功后系统自动创建，通常几分钟内完成。IP、SSH 端口等登录信息请在客户中心对应产品页查看（为安全起见 SSH 使用随机端口，不是 22）。Servers are created automatically after payment, usually within minutes. Your IP, SSH port and login details are shown on the product page in the client area (SSH uses a random port, not 22, for security).

目前支持支付宝（经 Stripe 安全收银台）和 USDT（TRC20 / BSC）。账单以美元计价，按所选周期预付，不会自动扣款。支付宝收银台会显示支付通道服务费，该费用不予退还；USDT 付款不支持退款。We accept Alipay (via Stripe secure checkout) and USDT (TRC20 / BSC). Invoices are in USD and prepaid for the selected cycle; nothing is charged automatically. Alipay checkout shows a payment channel fee, which is non-refundable; USDT payments are non-refundable.

开通前取消，或开通后 72 小时内因我们的原因无法正常使用，可以申请退款：只支持支付宝原路退回，支付通道服务费不退，退还其余部分。退款只能在用户中心「账单 → 申请原路退款」页面提交，工单、邮件申请不予受理。其他情况开通后不予退款，账户余额不退。详见 退款政策。If you cancel before provisioning, or the service cannot be used properly due to our fault within 72 hours, you can request a refund: Alipay payments only, refunded to the original account, minus the non-refundable payment channel fee. Refunds can only be requested on the Billing → Refund Request page of the client area; tickets and emails are not accepted. Otherwise services are non-refundable once provisioned, and account balance cannot be withdrawn. See our Refund Policy.

不会。我们不保障数据安全，也不提供数据备份，请您自行定期备份重要数据（例如定期把数据同步到其他服务器或本地）。硬件故障、被入侵、误操作、重装系统或服务到期终止都可能导致数据丢失且无法恢复，我们对数据丢失不承担责任。No. We do not guarantee the safety of your data and do not provide backups — please back up important data yourself regularly (for example by syncing it to another server or to your own computer). Hardware failure, compromise, mistakes, reinstallation or expiry of the service can all cause permanent data loss, and we are not liable for any data loss.

禁止垃圾邮件、攻击、扫描、挖矿、侵权等违法违规用途，禁止开放代理和 Tor 出口节点。允许转售，也可以把服务器分给您的用户或搭建需要认证的代理、VPN，但您要对下游用户和由此产生的投诉负责。完整规则见 服务条款。Spam, attacks, scanning, mining, infringing content and other unlawful use are prohibited, as are open proxies and Tor exit nodes. Reselling is allowed, and you may share a server with your own users or run authenticated proxy or VPN services, but you are responsible for your users and any complaints they cause. See our Terms of Service.
