A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables a computer or network-enabled device to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security and management policies of the public network. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. Major implementations of VPNs include OpenVPN and IPsec.
A VPN connection across the Internet is similar to a wide area network (WAN) link between websites. From a user perspective, the extended network resources are accessed in the same way as resources available within the private network. One major limitation of traditional VPNs is that they are point-to-point, and do not tend to support or connect broadcast domains. Therefore communication, software, and networking, which are based on layer 2 and broadcast packets, such as NetBIOS used in Windows networking, may not be fully supported or work exactly as they would on a real LAN. Variants on VPN, such as Virtual Private LAN Service (VPLS), and layer 2 tunneling protocols, are designed to overcome this limitation.
Changing your IP will help you not only to unblock restricted websites, but also to hide your identity and protect your personal data from being stolen. When can it be stolen? It can be stolen whenever you access your bank accounts, registering on certain sites or you connect to a public Internet. Changing your IP when browsing online is another benefit that VPN service come with.Privacy
You do a lot of things on Internet. You buy goods, watch media, listen to music, chat with friends, play and you can count on. The problem of the Internet nowadays is that your ISP, Network administrator or even some bad guys can relatively easy see everything you do while surfing. Because of encryption, VPN keeps all your Internet activity private, far from any unwanted eyes.Security
Not only hackers, but anyone who work on computer needs protection on the Internet during the actions. When working online you donít want your data (personal information like name, credit card number, passwords etc.) to be transferred or controlled. VPN creates a safe connection between you and our servers and this protection is really hard, almost impossible to break, unlike your basic protection.
