Python解析IP地址CIDR的形式

方法一：使用IPy库

>>> from IPy import IP
>>> ip = IP('127.0.0.0/30')
>>> for x in ip:
...  	print(x)       ##print前需要有tab空格
...                        ##此处回车即可
127.0.0.0
127.0.0.1
127.0.0.2
127.0.0.3

方法二：使用netaddr库

• CIDR也能直接转成IP地址段

>>> from netaddr import *
>>> ip = IPNetwork('192.0.2.16/29')
>>> ip_list = list(ip)
>>> print(ip_list)
[IPAddress('192.0.2.16'), IPAddress('192.0.2.17'), IPAddress('192.0.2.18'), IPAddress('192.0.2.19'), IPAddress('192.0.2.20'), IPAddress('192.0.2.21'), IPAddress('192.0.2.22'), IPAddress('192.0.2.23')]

>>> from netaddr import *
>>> startip = '208.130.29.30'
>>> endip = '208.130.29.35'
>>> cidrs = netaddr.iprange_to_cidrs(startip, endip)
>>> for k, v in enumerate(cidrs):
...     iplist = v
...     print iplist
...
208.130.29.30/31
208.130.29.32/30
