Is there native .NET type for CIDR subnets?

匆匆过客 提交于 2019-12-04 16:28:18
问题 It's simple enough to code up a class to store/validate something like 192.168.0.0/16 , but I was curious if a native type for this already existed in .NET? I would imagine it would work a lot like IPAddress : CIDR subnet = CIDR.Parse("192.168.0.0/16"); Basically it just needs to make sure you're working with an IPv4 or IPv6 address and then that the number of bits your specifying is valid for that type. 回答1: No there is such native type in .NET, you will need to develop one your self. 回答2:

IP address conversion to decimal and vice versa

做~自己de王妃 提交于 2019-12-04 15:12:04
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?? What is the reason behind it?? You could use this calculator for calculations. Vincenzo Pii IPv4

Django Forms clean() method - need IP address of client

落爺英雄遲暮 提交于 2019-12-04 14:37:07
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? So give yourself a reference to it. class MyModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop('request', None) super(MyModelForm, self).__init__(*args, **kwargs) def clean(self): ip_address = self.request['META']['REMOTE_ADDR'] and in your

change proxy on mac osx programmatically

一个人想着一个人 提交于 2019-12-04 14:21:08
How does one programmatically change proxy settings on a mac osx. I am fluent in ios, and since mac os programming is similar there shouldn't be much problems with it. However I lack the logic needed to create proxy changes programmatically.. Manual tweaking is extremely easy. This is the network tab in System Preferences I am after: What I have tried: let dynamicStore: SCDynamicStoreRef = SCDynamicStoreCreate(nil, "setProxy" as CFString, nil, nil)! let updated = SCDynamicStoreSetValue(dynamicStore, "HTTPProxy" as CFStringRef, "111.222.333.1") // updated is false, indicating unsuccessful

How to convert standard IP address format string to hex and long?

与世无争的帅哥 提交于 2019-12-04 12:37:43
问题 Does anyone know how to get the IP address in decimal or hex from standard IP address format string ("xxx.xxx.xxx.xxx")? I've tried to use the inet_addr() function but didn't get the right result. I tested it on "84.52.184.224" the function returned 3770168404 which is not correct (the correct result is 1412741344). Thanks! 回答1: The htonl, htons, ntohl, ntohs functions can be used to convert between network and local byte orders. 回答2: You have just got the bytes reversed from what you

Python: packing an ip address as a ctype.c_ulong() for use with DLL

。_饼干妹妹 提交于 2019-12-04 12:31:24
given the following code: import ctypes ip="192.168.1.1" thisdll = ctypes.cdll['aDLL'] thisdll.functionThatExpectsAnIP(ip) how can I correctly pack this for a DLL that expects it as a c_ulong datatype? I've tried using: ip_netFrmt = socket.inet_aton(ip) ip_netFrmt_c = ctypes.c_ulong(ip_netFrmt) however, the c_ulong() method returns an error because it needs an integer. is there a way to use struct.pack to accomplish this? The inet_aton returns a string of bytes. This used to be the lingua franca for C-language interfaces. Here's how to unpack those bytes into a more useful value. >>> import

Determining the IP address of a connected client on the server

空扰寡人 提交于 2019-12-04 11:42:39
I have a server running on one machine and have the port it uses forwarded to my router, and another machine running the client connecting to the server using my ISP assigned external IP address instead of the local address. This all works fine and it connects but When I check the address of the connected socket (client), The IP address that it shows is completely different? it shows me 148.49.68.0 . I can't find this on ipconfig and don't understand where this is popping up from. Shouldn't the client show my external address? (seeing as both computers use the same External IP address). [EDIT]

Binding a new SoapClient to a specific IP address before sending outgoing request

旧街凉风 提交于 2019-12-04 11:27:49
Let's say a machine where the application sits on has SoapClient (to be specific, I'm using Microsoft.Web.Service3.Messaging.SoapClient). It communicates toward a remote location with no problem by sending outgoing requests and getting SoapEnvelope in return (well-established process). The above scenario is through the IP assigned to the machine where the application is sitting on. Now, I need to modify this process - we need to add 2 more IPs to the machine, and I need to "bind" outgoing requests to a specific IP, rather than the default IP. So, at the remote location, it appears as if it is

Best type for IP-address in Hibernate Entity?

老子叫甜甜 提交于 2019-12-04 10:44:55
What is the best type for storing IP-addresses in a database using Hibernate? I though Byte[] or String, but is there a better way, or what do you use? @Column(name = "range_from", nullable = false) public Byte[] getRangeFrom() { return rangeFrom; } public void setRangeFrom(Byte[] rangeFrom) { this.rangeFrom = rangeFrom; } I store it in a long , very fast for lookup. You can use the following functions for conversion. public static string GetStandardIP(long numericIP) { string w = Convert.ToString(Convert.ToInt64(numericIP / 16777216) % 256); string x = Convert.ToString(Convert.ToInt64

Express.js: How can I get the ip Address and render a view?

和自甴很熟 提交于 2019-12-04 10:26:04
I really think this should be easy. But when I render a jade template, I also want to grab the ip address. My code look like this. app.js app.get('/', index.home) index.js exports.home = function(req, res) { res.render('index'); }; Where can I add something like: var ip = req.header('x-forwarded-for') || req.connection.remoteAddress; //or console.log(req.connection.remoteAddress); Just use req.ip and make sure you have app.enable('trust proxy'); if your app is deployed behind a reverse proxy. Express has all the header parsing and proxy logic baked in for you. 来源: https://stackoverflow.com
