ip-address

问题 How to pass IPAddress to webBrowser control This is my code but i don't know how to pass ip-address to webBrowser control. IPHostEntry host; string localIP = "?"; host = Dns.GetHostEntry(Dns.GetHostName()); foreach (string line in File.ReadAllLines("proxy.txt")) { IPAddress ip = IPAddress.Parse(line); if (ip.AddressFamily.ToString() == "InterNetwork") { localIP = ip.ToString(); textBox1.Text = ip.ToString(); // This code doesn't work, it's just a hypothetical example: webBrowser1

问题 As the title said, I want to match ip address with batch in windows, please tell me how I can do it? I see that " findstr " can match with regex like " [0-9] ", but how can "findstr" matches it appears one to three times ? 回答1: Since findstr 's regex support is a bit ... dated, you usually can't use most regexes you find on the web. The following matches four runs of digits, separated by dots: ipconfig | findstr /r "[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*" However, if you're only

问题 I'm trying to retrieve the IP Address of the local machine in my program. The Operating System is Ubuntu 8.10 . I tried using gethostname() and gethostbyname() to retrieve the IP Address . The answer I received is 127.0.1.1 . I learned that it seems to be a Debian thing: The document linked here explained the idea. The content of my /etc/hosts file is: 127.0.0.1 localhost 127.0.1.1 mymachine In this case, is there any other way to programmatically (prefer C or C++) to get the IP Address

问题 How can I get the same IP Address I get when I go to "http://www.whatsmyip.org/" using C++ and winsock library? I know how to get the "127.0.0.1" and the router IP "192.168.1.103"... But when I got to "http://www.whatsmyip.org/" I get "65.55.105.132"... How can I accomplish this? 回答1: In a general way - you can't. You could open an http connection to whatmyip and parse the result. Or as Justin suggests in the comments, use http://www.whatismyip.com/automation/n09230945.asp and save on parsing

问题 Either with PHP or a RegExp (or both), how do I match a range of IP addresses? Sample Incoming IPs 10.210.12.12 10.253.12.12 10.210.12.254 10.210.12.95 10.210.12.60 Sample Ranges 10.210.12.0/24 10.210.12.0/16 10.210.*.* 10.*.*.* I know that I can do this: ?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?) ...but it doesn't take ranges into account. It merely lets you match an incoming number to see if it's an IP address where each octet is 0-255. EDIT:

问题 I have a web server running out of my home. I have assigned it an address such as 192.168.1.123 on port 80. I understand that this is running on my local network. If I go to another computer on my network and type in the server's ip address, I can see the server. Is there a way to access this server from outside my LAN? 回答1: Yes, you need to set your router to forward connections to port 80 to your internal IP address (192.168.1.123). Look for Port Forwarding on your router admin screen which

问题 Currently in order to save an IP address I am converting it to number and store it in the collection. Basically I am doing this for logging purposes. This means that I care to store information as fast as possible and with smallest amount of space. I will be rarely using it for querying. My ideas that Storing as strings is for sure inefficient. Storing as 4 digits will be slower and will take more space. Nonetheless I think that this is an adequate method, but is there a better one for my

问题 I need a client side API in either Java or Ruby. I would much prefer need this to be LOCAL only. Infact this might not even be an IP, but more of a database import. The thing is that I cannot make use of a web service based one as that is too much heavy I/O for me. Note: By geolocation, all I really need is country/region at best. I would accept actual lat/long cordinates as well. 回答1: I was looking at these guys a couple months ago: http://www.maxmind.com/app/geolitecountry It seemed OK, for

问题 On Heroku Cedar, I wanted to get the client's IP. First attempt: ENV['REMOTE_ADDR'] This does not work, of course, because all requests are passed through proxies. So the alternative was to use: ENV['HTTP_X_FORWARDED_FOR'] But this is not quite safe, is it? If it contains only one value, I take this. If it contains more than one value (comma-separated), I could take the first one. But what if someone manipulates this value? I cannot trust ENV['HTTP_X_FORWARDED_FOR'] as I could with ENV[
