Every computer has its own IP address, and it is through this naming system that computers can connect with each other and share data.
Determining user location using the user IP address
A standard IP address using what's known as the IPv4 protocol contains four individual numbers separated by a decimal. While every computer is given its own IP address, the outside world rarely has access to it. Routers, instead, connect to individual computers, and it's the routers that then connect to the rest of the internet using their own individual IP address. Think of routers as the bridge between the network within your house or business, library, coffee shop, etc. When you send an email or visit a website, the IP address being shared is that of your local router — provided by your Internet Service Provider ISP — and not the individual address assigned to your computer.
All the same, whether someone knows the address of your computer or your network, these numbers are able to tell a bit about who you are and what kind of sites you surf. This most personal kind of information that can be shared in IP address itself is geolocation. But the good news is, because you are connected to a network and it's the network's IP address being shared, your precise location is not shared. Instead they'll probably see the information of your ISP. While this may give geolocation data about the general area of your router, it will not give a street address.
Alone, the IP address can't share much more about you than a generalized location of where you might be at a certain time. The trouble is, onlookers can in some cases look at the online activity associated with a particular IP address. All have online services, however. That will get you -- the address of the IP's registered owner, but -- not your client's location -- you must get that from them and also -- you have to ask for it. Also, proxies are the least of your worries when validating the IP that you think is the originator. People do not appreciate the notion that they are being tracked, so -- my thoughts are -- get it from your client directly and with their permission and expect a lot to balk at the notion.
Assuming you want to do it yourself and not rely upon other providers, IP2Nation provides a MySQL database of the mappings which are updated as the regional registries change things around. I like the free GeoLite City from Maxmind which works for most applications and from which you can upgrade to a paying version if it's not precise enough.
And if you are running Lighttpd as a webserver, you can even use a module to get the information in the SERVER variable for every visitor if that's what you need.

My city was Rasht and my country was Iran with this ip address: 2. I recommend to use database rather than API methods, because it will be processed much faster locally. There 2 broad approaches to perform IP geolocation: one is to download a dataset, host it on your infrastructure and maintain it up-to-date. This requires time and effort, especially if you need to support a high number of requests. Another solution is to use an existing API service that manages all the work for you and more. Here is an example to get IP geolocation information but also threat and user agent data using one call :.
