Python 網絡編程 netaddr

 

 

 

 

 1.安裝 netaddr 組件

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 <=============')
# 修改地址的掩碼長度為28
ip.prefixlen = 30
print(ip)

print('網絡地址 => %s' % ip.network)
print('網掩碼位 => %s' % ip.prefixlen)
print('子網掩碼 => %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數量 => %s' % ipIdx)
print('廣播地址 => %s' % ip.broadcast)

print('============> 以上實現了網站中獲取的信息 <=============')

 

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

from netaddr import IPAddress

# 判斷地址的公網、私網屬性
print(IPAddress("121.224.143.188").is_private())
print(IPAddress("192.168.0.1").is_private())
