0x01 代码思路：

利用二进制遍历：

1.将IP地址分割，每一块转换为8位二进制代码

2.将32位二进制代码转化为十进制，结束地址的十进制减去开地址的十进制，就可以得到之间的IP个数

3.从开始地址起，对其十进制数依次加一，再将其转化为二进制，即可得到之间某一IP的二进制代码

4.将这一IP的二进制按8位分割，每8位转化为一个十进制数，加上”.”，即可得到最终的IP

base = [str(x) for x in range(10)] + [ chr(x) for x in range(ord('A'),ord('A')+6)]

#十进制0~255转化为二进制,补0到8位

        mid.append(base[rem])

    result = ''.join([str(x) for x in mid[::-1]])

    length = len(result)

    if length < 8:

        result = '' * (8 - length) + result

    return result

#十进制0~255转化为二进制,补0到32位

    return result

        address = address_a + '.'+ address_b +'.'+ address_c +'.'+ address_d
