建议支持IPv6，无法通过你的IP验证，建议使用广播地址！

直接从CSDN上扒的，直接局域网广播就不需要一个一个发了...

ipv4_addr = "192.168.1.1"
ipv4_netmask = "255.255.255.0"

# 求IP广播地址
ip = ipv4_addr.split('.')
netmask = ipv4_netmask.split('.')
ip = [int(bin(int(octet)),2) for octet in ip]
netmask = [int(bin(int(octet)),2) for octet in netmask]
# 使用异或方法最终获得广播地址
broadcast = [(ioctet | (moctet^0xff))  for ioctet, moctet in zip(ip, netmask)]
