HZ的机器有内网IP吗？

我想用一台机器跑DB，万一业务机器宕机了不就暴露DB外网IP了。

我谷歌查了下，说是这个是按照流量收费的，每G/1欧？

Traffic
Internal traffic (across locations) is free of charge. For the public subnets, vSwitches have an included traffic limit of 1TB per month. Each additional TB costs € 1.00 per month (excl. VAT). We at Hetzner only count outgoing traffic for this price; incoming and internal traffic is free.

Important note: The main NIC is used for vSwitch traffic. An additional NIC for the vSwitch function is not necessary.

太简单了直接hosts指定……
data.com 然后用data.com就行
