1. 检查ip的有效性：

示例代码：

import ipaddress


# 检查ip的有效性
def check_valid_ip(ip):
    try:
        ipaddress.ip_address(ip.strip())
        return True
    except Exception as e:
        print(e)
        return False


if __name__ == '__main__':
    ips = ['192.168.1.1', '192.168.1.366', '10.25.1.36']
    for ip in ips:
        res = check_valid_ip(ip)
        if res:
            print(ip, res)
        else:
            print(ip, res)

运行结果：

2.判断IP是内网还是外网

示例代码：

import ipaddress


# 判断ip是内网还是外网
def check_ip_is_internet(ip):
    try:
        return ipaddress.ip_address(ip.strip()).is_private
    except Exception as e:
        print(e)
        return False


if __name__ == '__main__':
    ips = ['192.168.1.1', '192.168.1.366', '10.25.1.36']
    for ip in ips:
        res = check_ip_is_internet(ip)
        if res:
            print(ip, res)
        else:
            print(ip, res)

运行结果：
