Python解析IP地址CIDR的形式

使用IPy库

 from IPy import IP
 ip = IP('127.0.0.0/30')
 for x in ip:
    print(x)      

127.0.0.0
127.0.0.1
127.0.0.2
127.0.0.3

使用netaddr库

 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
