Python 网络编程 netaddr

1.安装 netaddr 组件

pip install netaddr -i https://mirrors.aliyun.com/pypi/simple/

from netaddr import IPNetwork

print('https://ipjisuanqi.com/#121.224.143.188')
ip_str = "121.224.143.188/28"
ip = IPNetwork(ip_str)
print(ip)
print('============> 30 <=============')
# 修改地址的掩码长度为28
ip.prefixlen = 30
print(ip)

print('网络地址 => %s' % ip.network)
print('网掩码位 => %s' % ip.prefixlen)
print('子网掩码 => %s' % ip.netmask)
ipIdx = 0;
for item in ip.iter_hosts():
    ipIdx = ipIdx + 1
    print('可用IP %s = > %s' % (ipIdx, item))
print('可用IP数量 => %s' % ipIdx)
print('广播地址 => %s' % ip.broadcast)

print('============> 以上实现了网站中获取的信息 <=============')

print('============> IPAddress的用法 <=============')

from netaddr import IPAddress

# 判断地址的公网、私网属性
print(IPAddress("121.224.143.188").is_private())
print(IPAddress("192.168.0.1").is_private())
