Masking or hiding your IP address using a VPN is a highly effective method of browsing the internet privately and securely. IP addresses contain information about the location of the user, and because of this, some sites respond in varying ways depending on the IP address of the user that is attempting to gain access. Because of this, it can be difficult to access certain parts of the internet from some physical locations. Using a VPN can get around this, however, it is important to be aware of where you want your IP address to be from, as this will affect what you have access to.
It is often considered undesirable to get an IP address from the United Arab Emirates due to the large number of restricted sites that are present. However, there are some reasons why this may be beneficial. One example of this is the fact that some content is available only to users within the United Arab Emirates, and therefore the only way to access this from outside the country is to get an IP from the United Arab Emirates. Another aspect is that for a person from overseas trying to access sites from the United Arab Emirates, speeds can often be painfully slow. Using a fake IP address from the United Arab Emirates can get around this, and allows for websites to be accessed much faster.
