## ip校验 ##

*  **对ip格式的校验，对于特殊的ip类型，需要单独再做判断筛选：**  
    方法一：
    
        import ipaddress
        
        ip = "0.0.0.0"
        try:
            result = ipaddress.ip_address(ip)
        except Exception as e:
            print("the ip is illegal")
        else:
            print("the ip is legal")
    
    方法二：
    
        import IPy
        
        ip = "1.1.1.1"
        
        try:
            result = IPy.IP(ip)
        except Exception as e:
            print("the ip is illegal")
        else:
            if ip == str(result):  # result是一个ip(IP对象)
                print("the ip is legal")

## ip/mask校验 ##

*  **仅校验ip/mask格式是否正确：**
    
        import ipaddress
        
        ip_mask = "1.0.0.0/24"
        result = ipaddress.ip_interface(ip_mask)
        if ip_mask == str(result):
            print("the ip/mask is legal")
 *  **校验ip/mask地址是否正确可达:**
    
        import ipaddress
        
        ip_mask = "1.1.1.1/32"
        try:
            result = ipaddress.ip_network(ip_mask)
        except Exception as e:
            print("the ip/mask is illegal")
        else:
            print("the ip/mask is legal")

## ip-ip校验 ##

*  **校验ip段，包括起始ip和结束ip格式是否正确，歧视ip和结束ip是否符合前小后大**
    
        import IPy
        
        ip = "1.1.1.1.1-1.1.1.11"
        ip_list = ip.split("-")
        if ip_list and len(ip_list) == 2:
            begin_ip = ip_list[0]
            end_ip = ip_list[1]
            
            try:
                begin_ip_int = IPy.IP(begin_ip).int()
                end_ip_int = IPy.IP(end_ip).int()
                
                if begin_ip_int <= end_ip_int:
                    print("the ip-ip is legal")
                else:
                    print("the ip-ip is illegal")
                    
            except Exception as e:
                print("the ip-ip is illegal")
        
        else:
            print("the ip-ip is illegal")
