There are occasions when it actually helps to know the place somebody who’s shopping your website is situated. There could also be no specific motive you may be in want of this info, however say you might be speaking to somebody who feels like, or may probably be, a scammer, and you have an interest in realizing the place they’re situated as a part of your private “risk evaluation.” In fact, simply because somebody may be (probably) shopping your website from behind a VPN or from a special nation than you expect is just not a motive to conclude that there’s malicious intent. However then again, if somebody you might be chatting with is claiming to be from a sure a part of say, the US, however a lookup of their IP tackle exhibits that consumer is in a special a part of the world, there may be a motive to be suspicious.
You could have observed a variety of photograph sharing websites provide the flexibility to find out which nation somebody is shopping from. This programming tutorial demonstrates one method to decide this info for your self.

What’s IP Handle Geolocation?
IP Handle Geolocation refers to both a bodily location related to an IP tackle, or to the act of getting that info. Even from the very beginnings of the Web, IP addresses at all times had some kind of geolocation information related to them. Within the broadest sense, you might search for the continent with which an IP tackle is related through IANA IPv4 Handle Area Registry, though within the case of this hyperlink, you would wish to substitute the whois server specified for the actual area of the world that it manages.
Quick ahead just a few many years and we now dwell in a world the place most computer systems, cell gadgets, and just about every part else has some kind of location-determining expertise and a few kind of Web connection built-in, and it was solely inevitable that near-precise willpower of a selected IP tackle’ geolocation would grow to be potential.
Scope and Limitations of IP Handle Geolocation
IP Handle Geolocation, because the identify implies, refers to places related solely with IP addresses. This may occasionally or might not correspond to the exact bodily location of a person laptop, cell gadget, or different expertise which has an Web connection. IP Handle Geolocation additionally doesn’t return any significant details about non-routable or personal IP addresses (e.g., 192.168.xxx.xxx or 10.xxx.xxx.xxx IPv4 addresses or IPv6 addresses which begin with fc or fd). The primary motive for it’s because many computer systems might share a single public IP tackle, as is the case with most cell gadgets.
IP Handle Geolocation can be extremely subjective. There is no such thing as a singular authority that information this info “in stone,” though there are a lot of providers which document such info. There are lots of totally different and probably conflicting sources of geolocation info for a selected IP tackle as properly, corresponding to:
- The situation supplied by the Web Supplier which owns the tackle in query.
- The situation-service-determined location of a number of gadgets which use or share an IP tackle.
- A VPN being utilized by a consumer to masks his or her bodily location.
So at finest, IP Handle Geolocation can provide you a ballpark estimate of the place a consumer could also be situated. With that being stated, there are nonetheless an awesome many issues that this info might be used for thus let’s bounce proper in.

Methods to Discover IP Addresses
In fact, we’ll want some supply materials to start our work. Say we’ve arrange a web site that hosts the next picture:
The picture of this stunning cat is within the Public Area, and is attributed as follows: “Cat” by Salvatore Gerace is marked with Public Area Mark 1.0. The unique picture might be downloaded from https://www.flickr.com/images/45215772@N02/18223540618.
On this specific instance server, this picture can be saved within the net root as me-medium.jpg. Most net servers, together with the one which hosts this specific website, use log recordsdata to trace the IP addresses which browse the positioning. This specific website, which is operating on Apache httpd inside a Docker Container, has the next log entries, together with one which was surprising:
Determine 2 – Instance Entry Log Entries
This net server being applied as a Docker Container has no bearing on it having log recordsdata. All correctly configured net servers, whether or not they run inside a Docker Container or on fully-virtualized environments or on precise bodily servers may have log recordsdata someplace. For Apache httpd, the log file location is often beneath the /var/log/apache2 or /var/log/httpd listing. The Apache httpd configuration recordsdata will specify the precise location. Regardless of the place the log recordsdata are saved, some kind of console entry, both through a direct login or an SSH session, can be wanted to entry the recordsdata. In most Apache httpd installations, root entry can be required.
Within the case of this specific website, a Docker Container was used as a result of it:
- Permits without cost utilization of root in a restricted setting, in a manner that can’t hurt the Docker host.
- Makes it straightforward to begin up or take down the positioning with out having to make configuration modifications on to the server itself.
- When run in interactive mode, it’s a lot simpler to edit configuration recordsdata and experiment with numerous settings than operating as a server daemon immediately.
There’s, after all, one main draw back. The cron daemon and Docker Containers actually don’t play properly collectively, particularly when making an attempt to run Apache httpd. Whereas the cron daemon and Apache httpd daemons might be run from the command line in interactive mode, operating them each collectively within the background is advanced and problematic.
The Apache httpd occasion inside this specific Docker Container shops its entry logs within the file /var/log/apache2/basic-https-access.log throughout the Container’s filesystem.
IP Handle Geolocation Providers
Geolocation can’t occur with no service that may present such info. A easy Google Search can present a number of IP Handle Geolocation Providers. Two that are free for restricted utilization are AbstractAPI and IpGeolocation API. Each of those providers require a consumer account and challenge API keys for programmatic utilization. Within the itemizing in Determine 2, I made a decision to attempt these APIs on the IP tackle 138.99.216.218, because it occurred to “randomly” hit my net server with a failed try at an exploit. Because the APIs for each AbstractAPI and IpGeolocation API are net based mostly, I used to be ready to make use of the next URLs to geolocate this IP tackle:
- AbstractAPI: https://ipgeolocation.abstractapi.com/v1/?api_key=your-api-key&ip_address=138.99.216.218
- Ip Geolocation API: https://api.ipgeolocation.io/ipgeo?apiKey=your-api-key&ip=138.99.216.218
AbstractAPI offers the next info:
Ip Geolocation API has a considerably totally different tackle this IP tackle:
Each providers ship information through JSON, and the FireFox browser mechanically codecs this info into an easy-to-read tabular format. Different browsers might present all of this info on a single line.
As for the IP Handle 138.99.216.218 particularly, we will see that it’s related to the nation of Belize. Sadly, no additional details about this IP tackle is obtainable. Distinction this to a different entry on this checklist, 102.165.16.221:
There’s positively much more info right here. Not solely do we all know that this IP tackle is related to the US, however we additionally know which metropolis and state throughout the US we’re coping with, particularly Trenton, New Jersey. We even get the ZIP Code, which additional nails down this specific location.
Past the nation info, there is no such thing as a rhyme or motive to what different info could also be supplied.
Now with the essential handbook course of outlined, we will transfer on to automating it. The subsequent part will clarify the way to use a Python script to parse the log file and get the data associated to every IP tackle.

Methods to Gather IP Geolocation with Python
The Python code beneath performs a fundamental evaluation of the log file /var/log/apache2/basic-https-access.log and makes use of the AbstractAPI software to search for the geolocation info for every IP within the log file that has browsed the me-medium.jpg file:
# parser.py
import json
import os
import re
import requests
import sys
# Go well with to style. Do not forget that utilizing the basis dwelling listing is barely acceptable when operating
# as a Docker container.
pathToCache = "/root/ip-cache/"

# Strip newlines from proper (trailing newlines)
currentLine = line.rstrip()
ipInfo = ""
dateTimeInfo = ""
#print ("[" + currentLine + "]")
if currentLine.__contains__(matchingFilename):
lineParts = currentLine.break up(' ')
#print ("Discovered IP [" + lineParts[0] + "]")
cacheFileName = pathToCache + lineParts[0] + ".json"
#print ("On the lookout for [" + cacheFileName + "]")
if os.path.exists(cacheFileName):

fp.shut()
# Get the nation and metropolis from the JSON textual content.

attempt:
metropolis = str(ipData["city"])

Observe: this script is not going to run if the requests module is just not loaded into Python through pip3.
This file has three notable options:
-
-
- It focuses on only one file being downloaded.
- It caches the outcomes of every API name.
- It saves its output to a different file which might be browsed on the positioning, particularly findings.html
-
Most API-delivered providers, even ones which can be paid for, impose some kind of restrict on the variety of instances they are often accessed, primarily as a result of they don’t need their very own servers to be overburdened. As a typical hit to an online web page can generate dozens, if not lots of, of traces in an entry log, it turns into an operational necessity to cache one name to the API for every IP tackle. Like all kind of caching, a scheduled job must be used to delete these recordsdata after a sure period of time.
Observe {that a} single net web page usually requires the downloading of not simply the HTML code, but additionally any photographs on the web page, together with any script recordsdata and stylesheet recordsdata. Every of this stuff leads to one other line within the log file from a given IP tackle.
This code is run through the command line:
$ python3 parser.py
After operating this code, it should have the next preliminary output:
Determine 6 – Preliminary output of parser.py
Observe: parser.py should be executed with adequate privileges in order that it might learn the Apache httpd log recordsdata and likewise write to the webroot listing.
After permitting for just a few hits from everywhere in the world to entry this picture, and operating this script as soon as once more, we see the next output:
Determine 7 – Up to date output of parser.py with just a few hits
It’s vital to notice that these outcomes usually are not calculated in actual time, this output is barely up to date on every successive run of parser.py. With that in thoughts, the easiest way to run this kind of evaluation could be to schedule this job to run through crontab.
Along with the outcomes web page in Determine 7, the next cache recordsdata had been additionally created, and every accommodates the JSON output downloaded from the API:
Determine 8 – Further output of parser.py
Armed with all of this new data, how may we use it to determine the place a possible consumer is from? Merely giving a consumer a URL from this server with a photograph may do the trick, assuming they browse to it. It is very important notice that this website was quickly hosted on an area broadband connection (discover the excessive numbered port?) so giving an unknown consumer one thing that factors on to your private IP tackle is unquestionably not a good suggestion! However, if in case you have hosted server house which you could run this on, you’ll positively be capable to get extra details about who you might be speaking to.
Closing Ideas on Python Geolocation
Geolocation has definitely gone a great distance from simply with the ability to inform with which continent a selected IP tackle is related. As you possibly can see, there may be fairly a major quantity of knowledge that may be harvested from these logs. Whereas easy flat recordsdata do properly for instance this from a proof-of-concept standpoint, you would possibly take into account extending this logic in order that it makes use of a database to handle this info as an alternative. Along with storing the processed outcomes, a database may also retailer the cached geolocation lookup outcomes as properly.
As many databases present sturdy evaluation instruments, web site directors could possibly higher gauge numerous metrics corresponding to which states or areas browse their websites probably the most or least, or how usually given IP addresses might “transfer round” from one location to a different. Little question that this info might be leveraged to customise or enhance the supply of service to finish customers, and far, way more.
