ip

问题 Just a quick question as I'm kind of new to math in PowerShell I need to make a converter in PowerShell that converts IP to Long. It works fine for lower values, but on higher ones it is causing an Integer Overflow. [int]$a = Read-Host "First bit of IP address" [int]$b = Read-Host "2nd bit of IP address" [int]$c = Read-Host "3rd bit of IP address" [int]$d = Read-Host "4th bit of IP address" $a *= 16777216 $b *= 65536 $c *= 256 $base10IP = $a + $b + $c + $d Write-Host $base10IP Works fine if I

问题 I want to be able to display the Country Flag image by the IP. The IPs are stored in Mysql in a column, each page has it's own row with IP like so: TABLE: PAGEID INFO IP 12340 abc 120.120.120.120 12341 fgh 121.121.121.121 12342 ert 122.122.122.122 12343 bvn 120.120.120.120 12344 hjk 123.123.123.123 So when a user open it will get the IP by the page id from mysql and then decide what country flag to display based on the IP. Is there such a script like this besides the one below? This is a

问题 I've been studying how to use sockets to make two java programs communicate. Now, on each example I've gone through, they've always placed the "server side program" on the same computer on which the "client side program" was, and of course the IP set was either 127.0.0.1 , or simply "localhost". Now, my question is: how do I get to communicate the two programs if one is on a computer, and one on another? I've tried to set the IP as the one my computer has when connected to internet (the one I

问题 I'm behind a transparent proxy which always adds the HTTP_X_FORWARDED_FOR header. When I dump the headers out using PHP the header is missing. But Python works.. lol Python: remote_addr = os.environ.get('HTTP_X_FORWARDED_FOR', os.environ.get('REMOTE_ADDR', '')) PHP: print_r($_SERVER['HTTP_X_FORWARDED_FOR']); print_r($_SERVER['REMOTE_ADDR']); ---- EDIT: Added more info on configs below ------ PHP Version: 5.2.16 PHP Configure Command: './configure' '--enable-bcmath' '--enable-calendar' '-

问题 I have written a PHP script which takes information about visitors IP and browser from a website and stores it in a table in my database. This script is included in the header and runs every time each page is loaded, google analytics type thing. survey.php I want this code to run only for each new visitor of the website, so that I only log each new visitor. I guess this is done by setting a cookie so I wrote this other code to set a cookie and then include the survey.php only when there is no

问题 Hi all, I am looking for a better solution for checking / calculating if an IP-address is in the same subnet like your iPhone. The background: I am looking up devices by the Zeroconf / Bonjour and this devices can have multiple IP-addresses. So I want to check which of them can be reached by my device. I Thought the easiest way is to take the extern IP and connect it with my subnet-mask, but I havenot found any way to do it directly (need both as int), so I made a workaround. The code:

问题 I need to validate if string entered in TextEdit is a web address eg. "www.stackoverflow.com" or an ip address eg. "64.34.119.12". I have tried this two methods without success.

问题 Can someone help me to checking a port scanner with specific range of IP addresses using command line. How can i make sure that the port scan with that IP's range. args[0] and args[1] for IP Address range, while args[2] and args[3] for a port scanner.

问题 I Use this code to get the public IP-address (thanks to this post How to get the IP address of the server on which my C# application is running on?): public static string GetPublicIP() { try { String direction = ""; WebRequest request = WebRequest.Create("http://checkip.dyndns.org/"); using (WebResponse response = request.GetResponse()) { using (StreamReader stream = new StreamReader(response.GetResponseStream())) { direction = stream.ReadToEnd(); } } //Search for the ip in the html int first

问题 I'm having bit of a trouble selecting correct values from my mysql sql server. The ip can be ipv6 and v4. Table: User{ ... ip binary(16) } $ip = '192.168.10.115'; $ip = bin2hex(inet_pton($ip)); // Returns c0a80a73 $result = $this->db->select("SELECT * FROM User WHERE HEX(ip) = $ip"); // $result empty because in db its stored as: // HEX(ip) = C0A80A73000000000000000000000000 How can I get a viable match to the * 00000 * ? If input was a ipv6 match this would be ok, but ip v4 not. 回答1: Can you
