VPN means ” Virtual Individual Network ” and actually describes a technology which allows you to safely access information in your exclusive network from all over the world.
VPN encrypts your internet connection beginning with your network cards up to a VPN server. This encryption occurs instantly and reliably avoids recording or listening to transmitted information. The sort of your Internet interconnection (modem, ISDN, GPRS, UMTS, LTE, cables, leased lines, WiFi), the decision of your machine or even the location what your location is, will not matter – your web connection is through the consumption of VPN totally encrypted.
Günstiges VPN is usually a self-contained subnetwork within a more substantial IP network where clients are actually separated (sometimes a large number of miles away). The participants connect to a login server with a VPN protocol (login servers can be found worldwide) and obtain their private new (interior) IP after establishing the encrypted tunnel. Given that the entire connection to the Internet is encrypted, computers outside this network can no longer read or change the communication. This means that the client laptop can communicate securely with selected various other computers. This is done with a virtual network card in the customer’s pc. This network card appears in the operating-system as a normal Ethernet adapter and is employed by the machine and also the programs as well, just the difference that the info transferred via this network card are automatically highly encrypted. In addition, adjustments of the VPN login server avoid the buyer from influencing each other, each client receives his very own tunnel and his unique encryption. All data sent or received is then sent by the server with a solitary IP (the IP of the respective VPN login server) to the Internet – this server IP pertains to all clients and guarantees anonymity again. May be the computer not connected to a VPN or even to a VPN supplier that distributes fixed ips,
Encryption via the inner, virtual VPN network card ensures that the Internet connection is not transparent to services, info collectors and additional computers in the local network and will not be designated to the Internet user.
Browsing with VPN encryption
A “normal” Internet connection such as UMTS / GPRS / ISDN / DSL etc. does not incorporate encryption by default: all the data you create (email, surf, chat, etc.) is certainly split into tiny packets and unencrypted by the TCP / IP protocol sent to the recipient.
Participants in regional networks, such as open public hotspots, can already listen to and record this data with simple means. Nonetheless it is also possible to park near your flat and tap your wifi via notebook.
Below can be an case in point for illustration:
You’re home and surfing through your WEP-encrypted Wi-Fi. Your neighbor has parallel “Wireshark” operate, a free plan for the research of network conversation links, and cuts with everything. Since WEP together with WPA are no more safe, it is not hard for your neighbor to create your WLan password from the info obtained. Within the next step, he surfs your series, monitoring your notebook computer instantly and getting mainly because a lot of your private data – your bank account details, your email accounts details, everything you shop when and where, who you’re chatting with, and so on.
In lots of countries, the Internet is certainly censored by the particular government, so that many offers (eg Facebook, YouTube, Wikipedia) are not available. In these cases, the Internet can not be fully used without a VPN connection, just the activation of the VPN gives you usage of all content worldwide.
