What is the difference between a proxy and a VPN

You have probably experienced it: access to many sites is impossible. This is the case for the ABC channel if you try to watch a series such as Grey’s Anatomy from France. But this would also be the case if you tried to watch M6 or TF1 from certain foreign countries: your access will be blocked. To fix this, you can use a proxy or a VPN. However, one of the two goes further than the other…

[EN VIDÉO] How to protect your IP address?
What is an IP address, what is it for and above all, how to protect it to prevent malicious software from stealing our data?

There are many situations where you may find yourself unable to access a movie, series, game or even a particular source of information. For example, the game Phantasy Star Online 2 has long been inaccessible in France. Those who were reluctant to wait for Sega to put it online on our soil, however, managed to access the servers Japanese because they concealed their IP via a proxy or one vpn. But what is the difference between the two?

Hide the Internet user’s IP address

There are a few points where these two types of service come together. The common point between proxy and VPN is that they are both dedicated to hiding the Internet user’s IP.

Let’s take a practical example. You want to connect to a site to which access is prohibited in France such as Crackle.com, a site offering various American films and series. Only then, access is denied to you. How does this work in practice?

IP addresses are made up of four sets of numbers, and reveal information such as:

  • the network used;
  • imprecise geolocation information but which may indicate the name of the country or the city;
  • the operator to which you are connected, for example Free, Orange, SFR, etc.

Firstly, operators such as Free or Orange operate according to what are called DNS, or global directories. When you type “crackle.com”, they consult these directories in order to convert this mention into a IP adress – in the case of crackle.com, this IP is as follows: 70.37.162.207.

However, the French operators have in these DNS lists of IP addresses that must be blocked – this is the case for several illegal download sites, revisionist sites, etc. Thus, it is possible that your operator operates by itself a blocking of access to this IP: 70.37.162.207.

Assuming that your operator has not blocked access, a site such as Crackle can itself analyze your IP address. As an example, Futura’s IP is 51.103.112.128. If an American site perceives, by analyzing such an IP, that the connection request comes from France, it can in turn refuse access.

If you are going through a proxy server or a vpnthis will serve as bridge : the request that is sent to crackle.com will go through an IP other than yours. This allows you to trick the crackle.com server into believing that you are connecting from the United States or another region where access is allowed.

Proxies

A proxy server comes between your computer and the server visited. This one will not be able to know what is your IP adress, it will only know the IP of the proxy server. If a large number of players wish to access the server of a given game, the use of the same proxy server is practical because all requests then pass via same address, which will improve the efficiency of their processing. Moreover, as we have seen, if the server of a video game based in Kyoto normally refuses access to French players, a proxy could give it the impression that they are connecting from Japan.

A proxy, on the other hand, does not hide the activity you have on the web. In other words, if you manage, via a proxy to access the site not accessible from France, it would be possible for a spyware to detect your activity.

VPNs

A VPN complements and extends the services of a proxy. Its role is to hide all of your activity from the outside world. The term itself VPN, Virtual Private Network (private virtual network) clearly specifies what it is: the VPN creates a kind of private and secure virtual tunnel, which isolates the exchanges between your computer and the server consulted.

A paid VPN service offers dozens of different IP addresses, with various locations: Chicago, Madrid, Shanghai… When you connect to the VPN, your information is routed through one of these servers. The site visited therefore does not know what your IP is and does not know where you are connecting from, it does indeed have the impression that you are actually connecting from Chicago, Madrid, Shanghai… And since the VPN encrypts the data exchanged , if someone wanted to spy on your web activity, they couldn’t analyze anything.

What do proxies and VPNs have in common?

  1. They conceal your IP address on Internet.
  2. They are compatible with the streaming and the game consoles.
  3. They tend to slow down computer activity.

What makes proxies different from VPNs?

  • Proxies can monitor your activity

There are many free proxy solutions, such as the proxy offered by HideMe. The flipside is that it’s not uncommon for proxy services to monitor your activity and may resell it to marketing companies – that’s their way of monetizing their service.

Conversely, VPNs, insofar as they encrypt your activity, allow completely discreet and anonymous browsing.

  • VPNs are usually paid

It is possible to use a free VPN but these are usually limited. Thus, a large number ofanti-virus integrate a VPN function but it will have various restrictions such as volume data exchanged via this service. Likewise, Opera browser offers free VPN service but it is itself limited to a small number of locations. Some premium VPNs offer free plans, including PrivadoVPN Where Hotspot Shieldbut generally limited.

The problem with using a free VPN is that they only offer a small number of alternative IP addresses. It is therefore relatively easy for companies such as netflix or Disney to detect these particular IP addresses and blacklist them.

If you want to have a very large number of IP addresses and therefore be able to browse without worry on sites such as those mentioned above, it is better to go through services such as NordVPN, HMA Where cyberghostand choose a paid offer.

  • VPNs work on multiple servers

A proxy usually works for single server access. A VPN will work on all kinds of sites and apps. However, there are services such as smartproxy which offers access to millions of IP addresses but of course, this particular proxy service is paid for.

  • Web Activity Encryption

We saw it above: the essential difference lies in the encryption (encryption) of your data. VPNs don’t just hide your IP address, they conceal all your activity. To take an example, with a proxy, whoever would try to spy on your activity could know which sites you have visited. If this discretion factor is essential, the use of a VPN is essential.

In summary

VPNs and proxies are complementary services, which ensure that your IP is hidden from the server consulted. However, a VPN has the advantage of encrypting all your activity and therefore protecting you from indiscretion, and it can work on all kinds of sites. Remember that it will, most of the time, afford a monthly subscription to make the most of such a service.
