我们可以将2行IP子网转换为整数，然后比较它们的大小关系。以下是代码示例：

import ipaddress

subnet1 = "192.168.0.0/24"
subnet2 = "192.168.1.0/24"

ip1 = int(ipaddress.IPv4Address(subnet1.split("/")[0]))
mask1 = int(ipaddress.IPv4Address(subnet1.split("/")[1]))

ip2 = int(ipaddress.IPv4Address(subnet2.split("/")[0]))
mask2 = int(ipaddress.IPv4Address(subnet2.split("/")[1]))

subnet_int1 = ip1 & (0xffffffff << (32 - mask1))
subnet_int2 = ip2 & (0xffffffff << (32 - mask2))

if subnet_int1 > subnet_int2:
    print("Subnet 1 is greater than subnet 2")
elif subnet_int1 < subnet_int2:
    print("Subnet 2 is greater than subnet 1")
else:
    print("Subnet 1 and subnet 2 are equal")
