Blocked websites can be bypassed by changing over to a different public DNS, by using a web proxy or by utilizing a VPN. Internet service providers may block a website by null routing to a local IP address, so when the website is loaded, a screen will show up that will say the website cannot be displayed.
Fortunately, an easy way to bypass a block on a website is to change the DNS that the computer uses. Doing this manually can be a very complicated task, which is why it may be easier to use a DNS Jumper. This is a free tool that allows the user to select a public DNS server quickly and bypass blocks that exist on the previous server. Many websites, such as Google, Comodo and Norton, offer public DNS servers that are free and operate at reliable speeds.
Another method that can be used to bypass blocks on websites is a web proxy. This is a great technique for someone who does not want to download any new programs on his or her computer. A web proxy website allows users to enter the blocked URL that he or she wishes to access. As long as the web proxy is not blocked by the ISP or the person's firewall, the web proxy will fetch the website and display it, acting as a kind of middleman to retrieve the website.
A VPN works very similarly to a web proxy, the only difference being that a VPN operates through an encrypted tunnel, affording faster speeds and more secure privacy. The downside to VPN services is they tend to cost money. Although there may be free VPN services available, their downside would be a probable downgrading in available bandwidth and speed.
