portant; overflow-wrap: break-word !important;">在了解这个问题之前，我们先需要了解下，什么是网络地址？
portant; overflow-wrap: break-word !important;">ipP地址是由两部分组成：网络地址+主机地址。
portant; overflow-wrap: break-word !important;">网络地址可以确定ip地址的范围，ip地址其实跟身份证号比较像。
portant; overflow-wrap: break-word !important; color: rgb(217, 33, 66);">portant; overflow-wrap: break-word !important;">一个人身份证：portant; overflow-wrap: break-word !important;">共18位：
portant; overflow-wrap: break-word !important;">前6位表示的是省、市、县区；
portant; overflow-wrap: break-word !important;">7到14位表示是出生年月，
portant; overflow-wrap: break-word !important;">15、16位表示是派出所。
portant; overflow-wrap: break-word !important;">第17位是性别。
portant; overflow-wrap: break-word !important;">而网络号就是相称于身份证的省、市、县区。
portant; overflow-wrap: break-word !important;">那么如何来算出网络地址呢？
portant; overflow-wrap: break-word !important; font-size: 15px;">具体计算
portant; overflow-wrap: break-word !important; font-size: 15px;">将ip地址192.168.1.1转换为二进制
portant; overflow-wrap: break-word !important; font-size: 15px;">11000000.10101000.00000001.00000001portant; overflow-wrap: break-word !important; font-size: 15px;">
portant; overflow-wrap: break-word !important; font-size: 15px;">将子网掩码255.255.255.0转换成二进制
portant; overflow-wrap: break-word !important; font-size: 15px;">11111111.11111111.11111111.00000000
portant; overflow-wrap: break-word !important; font-size: 15px;">然后将两者相“与（and）运算：

portant; overflow-wrap: break-word !important; font-size: 15px;">11111111.11111111.11111111.00000000
portant; overflow-wrap: break-word !important; font-size: 15px;">然后得到：
portant; overflow-wrap: break-word !important; font-size: 15px;">inkMacSystemFont, Helvetica Neue, PingFang SC, Hiragino Sans GB, Microsoft YaHei UI, Microsoft YaHei, Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important; overflow-wrap: break-word !important;">11000000.10101000.00000001.00000000
portant; overflow-wrap: break-word !important; font-size: 15px;">转换成网络地址就是：192.168.1.0
