在做测试时需求一些列IP地址，需要一个函数生成大量的无规律的IP地址。下面有一种方法，所以生成IP地址，而且一行代码就解决了。

IPv6随机生成

类似地，如果要生产IPv6，根据IPv6的结构修改范围即可。

# 示例

ip = ipaddress.IPv4Address('34.153.145.212')
print(ip.is_global) # True

# 嵌入到原来代码中
# 这里需要递归处理，如果生产的IP地址不是global类型，重新调用本身

def rip():
    ip = '.'.join([str(int(''.join(
    [str(random.randint(0, 2)), 
     str(random.randint(0, 5)), 
     str(random.randint(0, 5))]
    ))) 
    for _ in range(4)])
    if ipaddress.IPv4Address(ip).is_global:
        return ip
    else:
        return rip()

引入ipaddress

如果引入ipaddress模块，还有更简单的方法生产随机IP地址。IPv4是32位地址，每一个地址都可以用一整数表示。范围从0-2**32-1(4294967296-1)

1
2
3
4
5
import random
import ipaddress

rip4 = lambda: ipaddress.IPv4Address(random.randint(0, 2**32-1)).exploded

类似地，IPv6是128位地址。

import random
import ipaddress

rip6 = lambda: ipaddress.IPv6Address(random.randint(0, 2**128-1)).exploded

for _ in range(10):
    print(rip6())

生成CIDR地址对应的IP地址集

CIDR地址形如“192.168.23.23/16”，我们想把它转换为对应的IP地址集，

import ipaddress
net = ipaddress.ip_network('223.33.66.64/27')
ips = [str(ip) for ip in net]
print(ips)

类似地，IPv6也如此。
