IP地址處理模塊IPy之多網(wǎng)絡(luò)計(jì)算

判斷IP地址和網(wǎng)段是否包含于另一個(gè)網(wǎng)段中

>>> IP('10.10.10.0/24')<IP('10.10.11.0/24')

True

>>> '10.10.12.11' in IP('10.10.11.0/24')   

False

>>> '10.10.11.11' in IP('10.10.11.0/24') 

True

網(wǎng)段兩個(gè)網(wǎng)段是否有重疊

>>> IP('192.168.0.0/23').overlaps('192.168.1.0/24')    #1表示有重疊

1

>>> IP('192.168.2.0/23').overlaps('192.168.1.0/24')    #0表示沒重疊

示例

根據(jù)輸入的IP或子網(wǎng)返回網(wǎng)絡(luò)、掩碼、廣播、反向解析、子網(wǎng)數(shù)、IP類型
