Python: IP地址子网计算器

Python代码：

import ipaddress


def ipadd_calc(ip_net):
    try:
        net = ipaddress.ip_network(ip_net, strict=False)
        result = '是否是私有地址：%s '  % str(net.is_private)
        result += '\n所属IP子网：%s' % net.with_netmask
        result += '\n所属IP子网：%s/%s （前缀表达法）' % (net.network_address, net.prefixlen)
        result += '\n网络号：%s ' % str(net.network_address)
        result += '\n广播地址：%s ' % str(net.broadcast_address)
        sum_C = int(net.num_addresses/256)
        if sum_C >= 1:
            result += '\n包含：%s个C' % sum_C
        result += '\nIP地址总数：%s ' % str(net.num_addresses)
        result += '\n可用IP地址总数：%s' % str(len([x for x in net.hosts()]))
        result += '\n起始可用IP地址：%s ' % str([x for x in net.hosts()][0])
        result += '\n最后可用IP地址：%s ' % str([x for x in net.hosts()][-1])
        result += '\n可用IP地址范围：%s ' % str([x for x in net.hosts()][0]) + ' ~ ' + str([x for x in net.hosts()][-1])
        result += '\n子网前缀长度：%d' % net.prefixlen
        result += '\n掩码地址：%s ' % str(net.netmask)
        result += '\n反掩码地址：%s ' % str(net.hostmask)
        return result
    except ValueError:
        return('您输入格式有误，请检查！')

if __name__ == '__main__':
    ip_net = '192.168.57.255/255.255.192.0'
    print(ipadd_calc(ip_net))
