在Python中,如果我有一个IP地址和一个子网掩码作为字符串,我该如何确定网络IP?
即。 IP = 10.0.0.20,掩码= 255.255.255.0将导致网络IP为10.0.0.0

模块ipcalc可以快速处理ip地址作为字符串:
import ipcalc
addr = ipcalc.IP('10.0.0.20', mask='255.255.255.0')
network_with_cidr = str(addr.guess_network())
bare_network = network_with_cidr.split('/')[0]
print(addr, network_with_cidr, bare_network)
IP('10.0.0.20/24') '10.0.0.0/24' '10.0.0.0'

好吧,我可能应该发布我所做的事情。它可以满足我的目的:
# Return the network of an IP and mask
def network(ip,mask):
network = ''
iOctets = ip.split('.')
mOctets = mask.split('.')
network = str( int( iOctets[0] ) & int(mOctets[0] ) ) + '.'
network += str( int( iOctets[1] ) & int(mOctets[1] ) ) + '.'
network += str( int( iOctets[2] ) & int(mOctets[2] ) ) + '.'
network += str( int( iOctets[3] ) & int(mOctets[3] ) )
return network

您可以使用内置的ipaddress库:
import ipaddress
network = ipaddress.IPv4Network('10.0.0.20/255.255.255.0', strict=False)
print(network.network_address)
结果:
10.0.0.0
