如何判断两个IP地址是否在同一个网段

<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; text-align: justify; white-space: normal; text-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">
<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; text-align: justify; white-space: normal; text-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; color: rgb(84, 84, 84); font-family: 微软雅黑, 宋体, 黑体, Arial, Helvetica, sans-serif; font-size: 15px; letter-spacing: 2px; text-align: left; text-indent: 30px;">在了解ip地址的网段之前，我们先来了解子网掩码，很多对网络了解不深的朋友都对子网掩码有些迷惑，不了解它是用来干什么的？
<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; text-align: justify; white-space: normal; text-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; color: rgb(84, 84, 84); font-family: 微软雅黑, 宋体, 黑体, Arial, Helvetica, sans-serif; font-size: 15px; letter-spacing: 2px; text-align: left; text-indent: 30px;">子网掩码不能单独存在，它必须结合IP地址一起使用。子网掩码只有一个作用，就是将某个IP地址划分成网络地址和主机地址两部分。
<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; text-align: justify; white-space: normal; text-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">
<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; text-align: justify; white-space: normal; text-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; color: rgb(84, 84, 84); font-family: 微软雅黑, 宋体, 黑体, Arial, Helvetica, sans-serif; font-size: 15px; letter-spacing: 2px; text-align: left; text-indent: 30px;">说的通俗的话，就是用来分割子网和区分那些ip是同一个网段的，那些不是同一网段的。
<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; text-align: justify; white-space: normal; text-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">
<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-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; color: rgb(84, 84, 84); font-family: 微软雅黑, 宋体, 黑体, Arial, Helvetica, sans-serif; font-size: 15px; letter-spacing: 2px; text-indent: 30px;">例如，两个人都叫张三，但一个张三是张家村的，另一个张三是张村的，那么如何区分这两个张三分别是属于那个村的呢？得让村长来区分，就可以准确的把各自的张三领回村，那么子网掩码就相当于村长，它就是用来区分ip该ip地址是属于那个网段的。
<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-indent: 2em; box-sizing: border-box !important; overflow-wrap: break-word !important;">

那么问题来了，如果要使这三个ip段在同一个网段内，那么这个大网段共同的子网掩码是多少呢？
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; font-size: 15px;">我们来分析下：
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; font-size: 15px;">将ip地址192.168.0.1转换为二进制

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; font-size: 15px;">ip段一：192.168.0.1/22

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; font-size: 15px;">这种portant; overflow-wrap: break-word !important; letter-spacing: 0.544px;">192.168.2.x/22形式的ip地址相信大家平时都见过，就是已经告诉了子网掩码了。
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; font-size: 15px;">也就是说他们共同的子网掩码二进制前面22个都是1。
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; letter-spacing: 0.544px; box-sizing: border-box !important; overflow-wrap: break-word !important;">portant; overflow-wrap: break-word !important; letter-spacing: 2px; background-color: rgb(255, 255, 255); font-size: 15px;">11111111 11111111 11111100 00000000
