In addition to REMOTE_ADDR and HTTP_X_FORWARDED_FOR there are some other headers that can be set such as: HTTP_CLIENT_IP HTTP_X_FORWARDED_FOR can be comma delimited list of IPs HTTP_X_FORWARDED HTTP_X_CLUSTER_CLIENT_IP HTTP_FORWARDED_FOR HTTP_FORWARDED I found the code on the following site useful: http://www.grantburton.com/?p=97
Storing an IPv4 address as a binary(4) is truest to what it represents, and allows for easy subnet mask-style querying. However, it requires conversion in and out if you are actually after a text representation. In that case, you may prefer a string format. A little-used SQL Server function that might help if you are … Read more
First, you need to configure your computer to get a static IP from your router. Instructions for how to do this can be found: here For example, let’s say you picked the IP address 192.168.1.102. After the above step is completed, you should be able to get to the website on your local machine by … Read more
You’ve probably miss-typed something above that bit of code or created your own class called IPAddress. If you’re using the .net one, that function should be available. Have you tried using System.Net.IPAddress just in case? System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse(“127.0.0.1”); //127.0.0.1 as an example The docs on Microsoft’s site have a complete example which works fine … Read more
You can use hostname command : ipaddr=$(hostname -I) -i, –ip-address: Display the IP address(es) of the host. Note that this works only if the host name can be resolved. -I, –all-ip-addresses: Display all network addresses of the host. This option enumerates all configured addresses on all network interfaces. The loopback interface and IPv6 link-local addresses … Read more
No you can’t – IP addresses get reallocated and reassigned from time to time, so the mapping of IP to location will also change over time. If you want to find out the location that an IP address currently maps to you can either download a geolocation database, such as GeoLite from MaxMind, or use … Read more
Neither of these headers are officially standardised. Therefore: What is the difference between HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR? – it is impossible to say. Different proxies may implement these, or may not. The implementations may vary from one proxy to the next, and they may not. A lack of a standard breeds question marks. Why would one … Read more
Pretty simple with Regular Expression (but note this is much less efficient and much harder to read than worpet’s answer that uses an Apache Commons Utility) private static final Pattern PATTERN = Pattern.compile( “^(([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\.){3}([01]?\\d\\d?|2[0-4]\\d|25[0-5])$”); public static boolean validate(final String ip) { return PATTERN.matcher(ip).matches(); } Based on post Mkyong
try this: public static String getClientIpAddr(HttpServletRequest request) { String ip = request.getHeader(“X-Forwarded-For”); if (ip == null || ip.length() == 0 || “unknown”.equalsIgnoreCase(ip)) { ip = request.getHeader(“Proxy-Client-IP”); } if (ip == null || ip.length() == 0 || “unknown”.equalsIgnoreCase(ip)) { ip = request.getHeader(“WL-Proxy-Client-IP”); } if (ip == null || ip.length() == 0 || “unknown”.equalsIgnoreCase(ip)) { ip = … Read more
You can get the client IP using Request service: $container->get(‘request’)->getClientIp();
