Virtual Private Network, generally called VPN, is an inspiration on tunnelling. The packets are built in VPN format and therefore encapsulated into other protocol's carrier. After that, those packets are transmitted in between VPN server and customer with de-encapsulating on receiving part. VPN could exist with any country's IP. Upon request, the provider can setup the particular VPN with its particular IP for any of those countries together with add on services and advantages to the clients.
One of the most amazing parts of VPN is to let someone modify the IP no matter where you are when you are in business trip or travelling. After you modify the IP, you can use it to surf those websites that are strictly for its users only. Hulu.com is one of TV Streaming Show Website in US, which is only for United State's residents. If you are not US resident and you want to log in this Hulu.com, you are not able to do so. Nevertheless, if you are using US VPN, the IP will automatically change to US IP. This will allow you to surf this website as it already recognizes the US UP. Besides Hulu.com, VPN is also applicable to Facebook and Twitter if you are in China as they blocked these websites there.

It can help to protect and avoid Internet Service Provider (ISP) of the website's owner to track our activities during surfing. The way that VPN does this is to make a connection with the server only and will not notify the activities that you did. You will only become an anonymous by hiding your real IP. By using a higher level of VPN encryption, it will cover your existing IP and protect in your internet browsing. As a result, no one will know your location as they just notice your VPN IP instead of the actual one. This is important especially during surfing at public areas via Wifi Hotspot.
