python自动化运维学习笔记2- 实用的IP地址处理模块IPy

2、实用的IP地址处理模块IPy

下载地址
https://pypi.python.org/packages/source/I/IPy/
安装

python setup.py install

2.1 - 判断IP地址版本

>>> from IPy import IP

>>> IP('10.0.0.0/8').version()

4

>>> IP('::1').version()

6

2.2 - 通过指定网段输出该网段的IP个数和地址清单

#!/usr/bin/python
#__*__ coding:utf-8 __*__
#Filename:ip.py

from IPy import IP

def main():
ip = IP('182.168.8.0/26')
print ip.len()
for x in ip:
print x

if __name__=='__main__':
main()

    

[root@lsn-linux ~]# python ip.py 

64

182.168.8.0

182.168.8.1

182.168.8.2

182.168.8.3

182.168.8.4

182.168.8.5

182.168.8.6

...

2.3 - 反向解析地址格式

>>> from IPy import IP

>>> ip = IP('192.168.8.1')

>>> ip.reverseNames()

['1.8.168.192.in-addr.arpa.']

2.4 - 判断为公网或私网

>>> IP('8.8.8.8').iptype()

'PUBLIC'

>>> IP('192.168.8.1').iptype()

'PRIVATE'

2.5 - 转换地址格式

>>> IP('192.168.8.1').int()   十进制

3232237569

>>> IP('192.168.8.1').strHex()  十六进制

'0xc0a80801'

>>> IP('192.168.8.1').strBin()   二进制

'11000000101010000000100000000001'

>>> print IP(0xc0a80801)  反向转换

192.168.8.1

>>> 

2.6 - 掩码格式转换

>>> print IP('192.168.8.0').make_net('255.255.255.0')

192.168.8.0/24

>>> print IP('192.168.8.0/255.255.255.0',make_net=True)

192.168.8.0/24

>>> print IP('192.168.8.0-192.168.8.255',make_net=True)

192.168.8.0/24

>>> print IP('192.168.8.0-192.168.8.255',make_net=False)

192.168.8.0/24

>>> print IP('192.168.8.0-192.168.8.255')

192.168.8.0/24

2.7 - strNormal方法，返回格式不一样

>>> IP('192.168.8.0/24').strNormal(0)  

'192.168.8.0'

>>> IP('192.168.8.0/24').strNormal(1)

'192.168.8.0/24'

>>> IP('192.168.8.0/24').strNormal(2)

'192.168.8.0/255.255.255.0'

>>> IP('192.168.8.0/24').strNormal(3)

'192.168.8.0-192.168.8.255'

>>> 

2.8 - 多网络计算方法

IPy支持类似于数值型数据的比较，以帮助IP对象进行比较：

>>> IP('10.0.0.0/24')<IP('11.0.0.0/24')

True

判断IP地址和网段是否包含在另一个网段中：

>>> '192.168.8.1' in IP('192.168.8.0/24')

True

>>> IP('192.168.8.0/26') in IP('192.168.8.0/24')

True

>>> 

overlaps判断两个网段是否存在重叠，返回1表示存在重叠，返回0表示不存在

>>> IP('192.168.8.0/26').overlaps('192.168.8.0/24')

1

>>> IP('192.168.8.0/26').overlaps('182.168.8.0/24')

0

>>> 

2.9 - 根据输入的IP或子网返回网络、掩码、广播、反向解析、子网数、IP类型等信息。

#!/usr/bin/python

#Filename:ip2.py

print'reverses address is:',ip.reverseNames()[0]
print'subnet is',len(ip)
else:
print'reverses address is:',ip.reverseNames()[0]
print'version is:',ip.version()
