ip-address

问题 I am overriding the clean() method on a Django form. I want to have access to the IP address of the client (assuming this is a bound form). If I had a reference to the request object, I could get it easily from META("REMOTE_ADDR"). However, I do not have a reference to the request. Any ideas on how this could be done? 回答1: So give yourself a reference to it. class MyModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop('request', None) super(MyModelForm,

问题 Suppose my decimal number is 9766322441 so its corresponding is 70.30.65.9 but when this IP address IC converted back, its gives some different decimal number 1176387849 ... and when I convert the IP address pf google.com i.e 64.233.187.99 then it gives the 1089059683 and reverse conversion gives the correct IP address i.e 64.233.187.99 ... My question is what is wrong with the the above mention number? I also try with 9579342332 but the same result. It gives the wrong reverse conversion??

问题 I made the mistake of using == for comparing IP addresses instead of using the equals() method of the IPAddress class in C#, which will result in the comparison of references instead of values. Since the solution I am currently working on is very large for a one-man project (> 100.000 lines of source code), I am very sure that I still have some of these wrong statements in my code. Is there any possibility to tell Visual Studio to find all occurrences of == operations on a specific class for

问题 I have to subnet a network from a single class C IP address. I have figured out the subnet mask and the broadcast address (I'm using subnet mask /28) but don't understand how to get the gateway address. Can anyone help me? 回答1: If subnet mask is 255.255.255.248 then number of masked bit will be 5, hence number of subnets = 2. The power number of masked bits = 2 the power 5 = 32 subnets, and the number of hosts per subnets = 2. The power (unmasked bit or 32- total number of network bits) = 2

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . Here's the problem, it's very simple (to understand..): I have 2 computers at home, they both have the same public IP address (e.g. 1.2.3.4). I have 1 computer at a coffee place (different network) so it has a different public IP address. I want to send a message (e.g. "hi") from the computer at the coffee place

问题 Here is my scenario. I have my device (android phone). And I know the IP address of another device (which is some remote device in the Internet) So how do I send data to the other device? Do I use protocols like Tcp or Udp? EDIT : And I know there are public IP addresses and private IP addresses (like when a device connects via WiFi). In such a case is it even possible to use Tcp or Udp??? 回答1: What you're looking to do is a common task with a common problem (but also with a common solution).

问题 I have two Ip Addresses, and I want to count how many Ip Addresses there are in the range between the two. Example: IP_START = "127.0.0.0" IP_END = "127.0.1.1" SUM_OF_IP_ADDRESS = 257 Does anyone know if python has anything to help me accomplish this? 回答1: Short solution using the ipaddress package. import ipaddress ip1 = int(ipaddress.IPv4Address(unicode('127.0.0.0'))) ip2 = int(ipaddress.IPv4Address(unicode('127.0.1.1'))) print ip2 - ip1 回答2: IP_START = "127.0.0.0" IP_END = "127.0.1.1"

问题 How can I get the client's IP address in CakePHP? It'd be $_SERVER['REMOTE_ADDR'] in plain PHP. I thought it's like all $_SERVER vars and can be accessed using env('VAR_NAME') , or getClientIP() in CakePHP, but it doesn't return the same results. Any ideas? 回答1: CakePHP 1.x : RequestHandlerComponent::getClientIp(); So to clarify: public $components = array( 'RequestHandler' ); Then in the controller method: $this->RequestHandler->getClientIp(); CakePHP 2.x & CakepPHP 3.x : RequestHandler:

I am trying the following code but it is returning server address - public string GetClientIP() { string result = string.Empty; string ip = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; if (!string.IsNullOrEmpty(ip)) { string[] ipRange = ip.Split(','); int le = ipRange.Length - 1; result = ipRange[0]; } else { result = HttpContext.Current.Request
