Python模块学习之IPy模块
IP地址规划是网络设计中非常重要的一个环节,规划的好坏会直接影响路由协议算法的效率,包括网络性能、可扩展性等方面,在这个过程当中,免不了要计算大量的IP地址,包括网段、网络掩码、广播地址、子网数、IP类型等。
python提供了一个强大的第三方模块IPy,最新版本(2017-11-16)为V0.83。

3.1、获取IPy版本
>>> import IPy
>>> IPy.__version__
'0.83'
>>>
3.2、获取ip地址的版本信息
>>> IPy.IP("10.0.0.0/24").version()
4
>>>
>>> IPy.IP("192.168.1.1").version()
4
>>>
3.3、通过指定网段输出该网段的ip个数和所有ip地址清单
ip=IPy.IP("10.8.10.0/24")
print ip,type(ip)
'''
10.8.10.0/24 <class 'IPy.IP'>
'''
print ip.len()
'''
256
'''
for i in ip:
print i
'''
10.8.10.0

10.8.10.4
.....
10.8.10.253
10.8.10.254
10.8.10.255
'''
3.4、查看指定的ip是私有ip还是公网ip
ip=IPy.IP("10.8.10.0/24")
print ip.iptype()
'''
PRIVATE
'''
print IPy.IP("8.8.8.8").iptype()
'''
PUBLIC

3.5、将IP地址转换成整数
#转换成×××
print IPy.IP("10.8.10.232").int()
'''

3.6、IP地址排序
###################ip地址排序############
L=['10.8.1.1','10.7.1.2','10.8.10.254','10.1.1.1']
L1=sorted(L,key=lambda x:IPy.IP(x).int())
for i in L1:
print i
'''
