import socket

def is_valid_ipv4_address(address):
    try:
        socket.inet_pton(socket.AF_INET, address)
    except AttributeError:  # no inet_pton here, sorry
        try:
            socket.inet_pton()
        except socket.error:
            return False
        return address.count('.') == 3
    except socket.error:  # not a valid address
        return False

    return True

def is_valid_ipv6_address(address):
    try:
        socket.inet_pton(socket.AF_INET6, address)
    except AttributeError:  # no inet_pton here, sorry
        try:
            socket.inet_pton()
        except socket.error:
            return False
        return address.count('.') == 3
    except socket.error:  # not a valid address
        return False

    return True

def checkStatus():
    websiteToCheck = input("Enter IP: ").replace(" ", "")
    if is_valid_ipv4_address(websiteToCheck) or is_valid_ipv6_address(websiteToCheck):
        print("Valid")
    elif len(websiteToCheck) == 0:
        print("Please input something")
    else:
        print("Invalid")

checkStatus()

当它无效时给出预期的输出，例如当数字超过255，输入包含字母等字母时。但是，让我们输入10.111.111.111作为我的IP。它打印＆＃34;有效＆＃34;，即使您现在尝试访问该IP，也会失败。

如何检查IP是否在线，而不是它是否在数字上有效？

Answer 1

您无法通过简单地查看是否可以访问IP。您需要尝试连接或ping它。后者很容易，虽然不是100％准确（并非所有IP都响应ping）

快捷方式：

import os
response = os.system("ping -c 1 " + address)

#check the response...
if response == 0:
  return True
else:
  return False

我的IP检查员正在检查IP在技术上是否有效，我想检查一下它是否在线
