4/27/2024 0 Comments Google maps ip address locationPublic static Boolean IsValidIP( string ip) Not all visitors are human-been, part of them could be search engine spiders, I must distinguish human visitors and spiders, otherwise for example, I will be happy to see a lot of "visitors" came from "Mountain View, CA" ^_^.įor #1: I use regular expression to validate the string I got from Request.UserHostAddress:.Malicious application can forge HTTP request with modified X-Forwareded-To header (for example: X-Forwarded-To: dangerous code), if you are unlucky to trust it and have it inserted into database, then SQL Injection hole will be utilized by malicious application.So, usually the server received the request and saw Via/X-Forwarded-For header information, it got to know visitor's IP address (NOT all the time, sometimes ISP's IP address), in ASP.NET, it is simply to call Request.UserHostAddress, however, we can never simply trust this because of two major reasons: The first task I need to do is track visitor's IP Address, most of the time, user visits a website in browser submits an HTTP GET request (an HTTP data package) based on Transmission Control Protocol (most of the time), browser passed the ball to DNS server and DNS server delivered the request to the designation - the web host server, during the process, the original Http request was possibly transferred through a number of routers/proxies and many other stuff, the request's header information might have been updated: Via (Standard HTTP request header) or X-Forwarded-For (non-standard header but widely used), could be the original ISP's information/IP Address OR possibly one of the proxy's IP Address. (P.S.: I've been used Google Analytics for my Geek Place - for more than two years, it is no double extremely powerful, and it already contains a feature "Map Overlay", however, due to privacy policy, Google Analytics does NOT display visitor's IP address, see ). So, the process is: Track visitor's IP addresses -> "Translate" them to Geography location -> Show them on Google Map! Just a few days ago, I casually emitted an idea: summarize those GEO location records and display them on Google Map, hmm, it is feasible:) Since beforehand I stored visitor's IP Addresses into my own database, I decided to utilize InfoDB API to store visitor's GEO locations. It provided API which could "translate" any IP Address into a geography location including City/Region/Country as well as latitude/longitude and time zone information, to invoke its API, a registered API key is required (which is free). You can also check for any IP address leaks by following our guide on how to make sure if Surfshark VPN is working.Few months ago, I found an interesting website. Connect to a completely different location.This may help you receive a new IP address, If you have connected to a freshly installed Surfshark server, it might be that Google did not update the IP location database, which led to a display of incorrect locations. If Google detects a significant number of devices using that IP address in a certain area, it will change its location for that IP address. Google determines user location by cross-checking the IP address with geolocation data of devices using that IP address. Google might show you a different location than the one you connected to for the following reasons: We will go through the following reasons and possible solutions: In this article, you will learn why sometimes Google shows a different country location rather than the one you connected to and how to remedy this.
