It would be very useful to get an Armenian IP address, if you are an Armenian citizen and are out of country for some reason. The question would be how to get an IP address from Armenia if you are living in a different country. This service to change your IP address is provided by VPN.
VPN is actually a Virtual Private Network that provides you a gateway to connect to the internet. This connection through gateway allows you security as well as the ability to appear to be at a place other than where you are. Moreover, since you are accessing the internet from another computer, your activities on the internet cannot be traced back to you and provide you the ultimate privacy.
Apart from providing security and the ability to surf the internet without being traced back to, there is one big use of the VPN. Since the advent of Internet many of the facilities have shifted to the internet. There are many government facilities as well as other shopping and bank services that can only be accessed if your IP address belongs to that country. Thus if you are living outside Armenia and want to access an Armenian facility from a foreign country using internet, you must get an Armenian IP address using an Armenian VPN.
Armenia is a pretty rare place to find VPN servers, but IAPS Security Store has this option. Visit their offical website through this like below to compare PPTP, L2TP, OpenVPN, and SSTP options.
