I found the ioctl solution problematic on os x (which is POSIX compliant so should be similiar to linux). However getifaddress() will let you do the same thing easily, it works fine for me on os x 10.5 and should be the same below. I’ve done a quick example below which will print all of … Read more
Since IPv4 addresses are 4 byte long, you could use an INT (UNSIGNED) that has exactly 4 bytes: `ipv4` INT UNSIGNED And INET_ATON and INET_NTOA to convert them: INSERT INTO `table` (`ipv4`) VALUES (INET_ATON(“127.0.0.1”)); SELECT INET_NTOA(`ipv4`) FROM `table`; For IPv6 addresses you could use a BINARY instead: `ipv6` BINARY(16) And use PHP’s inet_pton and inet_ntop … Read more
Extra server variables that are available to cloud flare are: $_SERVER[“HTTP_CF_CONNECTING_IP”] real visitor ip address, this is what you want $_SERVER[“HTTP_CF_IPCOUNTRY”] country of visitor $_SERVER[“HTTP_CF_RAY”] $_SERVER[“HTTP_CF_VISITOR”] this can help you know if its http or https you can use it like this: if (isset($_SERVER[“HTTP_CF_CONNECTING_IP”])) { $_SERVER[‘REMOTE_ADDR’] = $_SERVER[“HTTP_CF_CONNECTING_IP”]; } If you do this, and the … Read more
From CLI PHP < 5.3.0 $localIP = getHostByName(php_uname(‘n’)); PHP >= 5.3.0 $localIP = getHostByName(getHostName());
The technically correct way to store IPv4 is binary(4), since that is what it actually is (no, not even an INT32/INT(4), the numeric textual form that we all know and love (255.255.255.255) being just the display conversion of its binary content). If you do it this way, you will want functions to convert to and … Read more
As it turns out, the recent WebRTC extension of HTML5 allows javascript to query the local client IP address. A proof of concept is available here: http://net.ipcalf.com This feature is apparently by design, and is not a bug. However, given its controversial nature, I would be cautious about relying on this behaviour. Nevertheless, I think … Read more
The following code finds all IPv4 and IPv6 addresses on an iOS or OSX device. The first getIPAddress method acts more or less as the older code in this answer: you can prefer either one or the other type address, and it always prefers WIFI over cellular (obviously you could change this). More interestingly it … Read more
Using ipaddress (in the stdlib since 3.3, at PyPi for 2.6/2.7): >>> import ipaddress >>> ipaddress.ip_address(‘192.168.0.1’) in ipaddress.ip_network(‘192.168.0.0/24′) True If you want to evaluate a lot of IP addresses this way, you’ll probably want to calculate the netmask upfront, like n = ipaddress.ip_network(‘192.0.0.0/16’) netw = int(n.network_address) mask = int(n.netmask) Then, for each address, calculate the … Read more
The solution is @RequestMapping(value = “processing”, method = RequestMethod.GET) public @ResponseBody ProcessResponse processData(@RequestParam(“workflow”) final String workflow, @RequestParam(“conf”) final String value, @RequestParam(“dc”) final String dc, HttpServletRequest request) { System.out.println(workflow); System.out.println(value); System.out.println(dc); System.out.println(request.getRemoteAddr()); // some other code } Add HttpServletRequest request to your method definition and then use the Servlet API Spring Documentation here said in 15.3.2.3 … Read more
Okay, as of 0.7.7 this is available, but not in the manner that lubar describes. I ended up needing to parse through some commit logs on git hub to figure this one out, but the following code does actually work for me now: var io = require(‘socket.io’).listen(server); io.sockets.on(‘connection’, function (socket) { var address = socket.handshake.address; … Read more
