<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; font-size: 17px; letter-spacing: 0.544px; white-space: normal; text-align: center; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important;">私网地址

portant; overflow-wrap: break-word !important;">除了这三个ip地址段为私有ip地址外，其它的都为公网ip。

portant; overflow-wrap: break-word !important;">这些地址已被声明私有化，任何内网中的设备可以任意使用这些地址，但是在这三个范围内的IP地址不允许出现在Internet（外网）上。

portant; overflow-wrap: break-word !important;">所以我们平时在做监控项目或内部组网时，就可以把ip地址设为192.168.x.x。

<p style="margin-top: 0px; margin-bottom: 20px; padding: 0px; max-width: 100%; box-sizing: border-box; overflow-wrap: break-word; clear: both; min-height: 1em; color: rgb(51, 51, 51); letter-spacing: 0.544px; text-align: justify; white-space: normal; border-width: 0px; border-style: initial; border-color: initial; font-family: PingFangSC-Regular, "PingFang SC", "Helvetica Neue", Helvetica, "Microsoft YaHei", Arial, "Hiragino Sans GB", sans-serif; font-stretch: inherit; line-height: 28px; vertical-align: baseline; widows: 1;">portant; overflow-wrap: break-word !important;">一般普遍使用端口映射的方式，NAT的核心是一张映射表（源IP地址，源端口，目的IP地址，目的端口），将内网源IP地址和端口映射到同一个公网地址的不同端口，如下图所示。
