Hiding your IP address online to remain anonymous

          In the last post, I demonstrated how anyone who knows your IP address can track your torrent downloads without your permission. If you are concerned about your privacy on the internet, the first and most important step to take is to mask your IP address. (Or stop whatever you are doing on the internet that makes you feel insecure -most things shouldn't. But then again, if you wanted to do that instead, you wouldn't be reading this.) Accessing blocked content is another bonus of masking your IP address.

        If you don't know what an IP is, it is an address used to identify your device in a network, and is required for normal communication on the internet. It will be a set of numbers, like "127.0.0.1". IP addresses are not unique to a device, but rather unique to a router. This means that all devices connected to your home WiFi will have the same IP address, but if you connect your laptop to your neighbor's WiFi, it will have a different IP address.

        If you are a user of wireless mobile data, you should be assigned a random IP address by your carrier each time you connect to the internet, most of the time, effectively eliminating the chances of someone tracking your activities via IP. If you don't use mobile data, or want your IP address to make it seem like you are in another region or another continent altogether, read on.

1.Use a proxy


        This is perhaps the quickest and easiest method to mask your IP. A proxy is an intermediate server, and when you use a proxy service, all your internet usage is redirected through a proxy server. So all the sites you visit can only see the IP address of the proxy server assigned to you, while your real IP remains anonymous. There are hundreds of free proxy sites on the internet -although several of these can contain malicious content. Hence, as with all things on the internet, use these at your own risk.

        www.dreamytricks.net/free-proxy-sites-server-list/ is a very useful and up-to-date list of some of the top online proxy services available today, the majority of them being completely free to use.

        Here I am using www.4everproxy.com , although all sites in that list should work in a similar way.



        All you have to do is enter the website you wish to access anonymously in the box on the bottom, and hit "Go to site".



        Here I have opened YouTube via 4everproxy. The bar at the top can be used to navigate to more websites as well. I find that my usual "trending in India" (Since I'm from India) section has been replaced with videos trending in the U.S instead, since the proxy server is located in the US. And just like that, I am able to become anonymous on the internet.


2.Use a VPN


        If the above section did not satisfy the Edward Snowden-inspired "Big brother is watching" enthusiast in you, then look no further than Virtual Private Networks, a.k.a VPNs. Fundamentally these are 'advanced' proxy systems, that offer antivirus filtering and high level encryption to every action you make on the internet while not keeping any logs of your usage anywhere. And when I say all actions on the internet, I do mean all actions, unlike proxies which only work within your browser.

        This super-secure layer on anonymity comes at a price however, as most reputed VPN services on the internet require a paid subscription to use. PCmag has a very good list here. But it's not all dark for those hoping for free VPNs, as a few of these does exist, albeit lacking many of the features of paid VPNs.

        A popular example of a free VPN is CyberGhost, which gives you several options (Some of them require purchasing the premium version, however.) and allows you to choose the country through which your traffic will be redirected. It doesn't have fancy features like ad-blocking and firewalls, but it does offer a high level of encryption, enough to make anyone feel secure.





        It is worth noting that using either proxies or VPNs will make your internet connection a bit slower, as all of your traffic has to be redirected through a server on a completely different part of the world.

So, there you have it folks. The only guide you need to stay in shadows when browsing the internet. Remember there is no such thing has complete anonymity online, but unless you did something to incur the wrath of the FBI or deadly hacking organisations, these should serve your purpose just fine.

I Know What You Download

        Privacy is perhaps the biggest issue booming around the netizen world over the past few years. From Edward Snowden to the outcry for end-to-end encryption on Whatsapp, people are always sensitive about who can see or track what they do on the internet, and for good measure. Being tracked on the internet is about as invasive as a person watching over everything you do, in real life. So I can only assume many users will be shocked if I told you I can tell you everything you have downloaded off popular torrenting websites, most of which would be illegal content.

        Well, I can't just do that, not without having your IP address anyways. Your IP address is used to identify your device on the internet, and every node that connects to the internet, such as your home WiFi or mobile device has it's own unique IP address. This information can be extracted very easily. In fact, every website you ever visit or any internet service you use can view your IP. This itself is not a privacy violation, as the IP address is required to communicate with your device. But once a person interested in stalking your download activity has your IP address, all they need to do is plug it into this website, aptly named "I know what you download", and your torrenting history lists itself, ready to be viewed by anyone's eyes. 



        Okay, so say you are interested in checking if your best friend's favorite midnight past time is downloading TV shows or watching porn. (Please, this is an explanation. Don't ever do that to anyone you sick stalker!). Problem is, you do not know his/her IP address. This website even allows you to get past that. All you have to do is find a website address, any address, to send your friend that you know he will click. Then enter it into the download tracker and hit 'Transform' to generate another URL. Send this to your friend, and let him click it. Everything will seem normal and the link will take him to the intended website. But what really happens is that the link goes to the iknowwhatyoudownload website, which captures his IP address, and then redirects him back to the original link. No suspicions aroused, and one successful IP capture done.



        The existence of websites like this is an ode to the fact that no one can truly remain hidden or cloak their activities while on the internet. You can only take the necessary precautions, and, well, make sure your list on nemeses don't include some creep who would stalk your internet activity.

        I shall soon follow up this post with some basic methods to hide your IP, so that trackers like this won't work on you. Meanwhile, mobile data users can remain safe in the knowledge that they are assigned a random IP address most of time they connect to the internet, preventing creepy trackers from stalking them. For the most part, at least.

            That's all for now, cheers! =)
