Actually, there are 2 interpretations of VPN.We speak in the professional world of a virtual private network if we want to expand a LAN (a local network of a school or a company) in the LAN itself, so in the same private address network.
There are 3 classes of IP addresses (in IP version 4) that are used for private networks.There is 10.0.0.0, 172.16.0.0 and 192.168.0.0
Everyone recognizes the 192.168.0.0 network from home.Companies and schools use this as well. A company can also perfectly use an IP of 192.168.0.10 for a computer while millions of other people also use this IP address at home, no problem.
The reason why this does not conflict is because a private IP address cannot pass through a router (though NAT, but that would distract us now).
So the REAL definition of a VPN is that I bvb.2 affiliates can have and that my LAN is not limited to my one branch office, I can use the network 192.168.0.0 in branch 1, this is the network address. And then I can start to share Ip’S to computers and servers from 192.168.0.1…
Now suppose you want to use this same network (LAN Network) in branch 2, then you put a VPN and even you can put your DHCP server (which will be handing out IP addresses) in branch 1 and still operate branch 2 in a safe way.
You then have 2 things that will be settled by that VPN.
- A tunnel is established between the routers of each branch.
Actually, this is also not really true, it is a kind of encapsulation that is used, a kind of extra secure envelope in which your package is stopped (I’m not going to make it too technical;-))
When you have these 2 together, you have a VPN.The servers in branch 1 do not realize that a client is in the same or in another branch office.
And then you have the VPN of the ‘ laymen ‘ (which is irreverently).This was mainly caused by the leechers who wanted to be able to download (torrents…) Without the limitations of country codes. For example, you can Use streaming services as if you were downloading from Canada. Please note that this is certainly NOT anonymous. I have been working with network management for 20 years and anonymous DOES NOT EXIST.
Very simple explanation (otherwise, if you ask another question, I can go deeper into it): every traffic ever is actually traffic between 2 unique addresses that are put into the appliance by the manufacturer of a network appliance (hardware).
The most famous is the MAC address, a hexadecimal address that consists of 2 parts, en. Make and serial number.There are no 2 equal MAC addresses! (You may be spoof)
So you really don’t need an IP address to make a network between computers, REALLY NOT!A big limitation of the MAC Ardes, however, is that it cannot pass a router, so you have to stay within the same network.
Since this is no longer this time, there is of course always an IP address that is distributed to a computer, usually via an automatic DHCP server.This way your PC also gets an IP address, e.g. 192.168.2.10
This IP address really only serves to be able to get out of your MAC network, to get past a router.But all communication is physically done first via MAC address. So PC 1 want to send something to PC2. PC1 has its MAC address and its IP address from its DHCP server. PC1 should now send something to PC 2 and has the destination IP address of PC 2, but he does not know the MAC address yet, that must be searched first by ARP (aDdress Resolution Protocol). If PC 1 then knows the MAC from PC 2 Then he can send the info.
So there is ALWAYS a PROTOCOL THAT DOES require TRANSLATION, and that is always logged and is always traceable, even Tor networks are NOT Anonymous, it only becomes trickier, especially if there are different countries and continents in between (politics).But you’re never working anonymously, your ISP even keeps all the search traffic, and even before that, there’s already a log of all your DNS traffic.
That is another difficult subject to explain briefly but:
If you enter a website domain in Google, you never actually communicate directly with that server that hosts that website, first the IP address of that server must be found.There is a translation protocol that translates (domain) names to IP addresses and that is called DNS (there is local and Internet DNS by the way).
You tap on your PC that domain in BVB.bol.com, you are going to do a whole series of searches, first to YOUR local DNS server and then via THE Internet DNS servers, until you KNOW the IP of Bol dot COM AND only then!!!Are you going to really communicate with that server from Bol dot com! So your DNS server knows perfectly where you surf, you’ve already thought about it???
You have solutions for this, but most ordinary people no longer have this and it doesn’t interest them anymore, it gets too complex…
You can eg.DNSSEC and DNS Crypt use but that’s for another post…
Hopefully you have something to it, I’m a lector so forgive me for the some long explanation, I tried to keep it short;-)

Your IP address.You’re IP address?You might mean your IP address of your home network that is often linked to your home subscription for a long time. So the IP address of the network you are on when you go to the Internet with your computer.
By using a VPN, traffic seems to get rid of your VPN Provider.This is easy to test with e.g. Google.A website or bit-torrent will see this IP address, not the address of the device you use the Internet with.
There are a few things you have to remember.Some VPN services deserve you again, especially if they are cheap or free. These services will also provide little resistance if they receive a data request, in addition, a VPN service can also be a security risk. Chose Choose.
Finally, another nice… https://iknowwhatyoudownload.com Here you can see what you have downloaded to bit-torrents lately (if you are not using a VPN).It also allows you to entice friends to click on a link so you can see what they have downloaded. Not neat, but hilarious.
This is basically possible since the TC/IP package also stores your own IP address.The question remains who can intercept the package in order to subject this to an in-depth investigation.
Typically, VPN services are intended to hide your IP address so that youCan use video services that are intended only for a particular country. For instance, you can only see Dutch TV on the Internet if you have a Dutch IP address. With a VPN service that must of course have Dutch IP addresses you can still see Dutch TV, even if you live in New Zealand….
Regular WWW sites as you come across when you are browsing the Web with your browser just look from where the request comes and not what IP address is stored in the TC/IP packages and then the IP address of the VPN service comes up and so it seems like you are in that country Where the VPN server is or is configured.
If you’re using a VPN network, you’ll get a new (virtual) network interface on your computer or phone, which has the IP address you use for VPN traffic.This can be an audience or a private IP address. If it is a private address, it will also be converted via a NAT to a public IP address by the VPN provider.
Based on purely your IP traffic, a site you’re going to can’t figure out what your real IP address is because it comes from a different network interface.
