You've heard of OpenDNS to improve your browsing, but you don't know what it is and how it should be used? Here you will find a small introduction where I will explain what DNS is and how OpenDNS can change the way you browse.

Eventually I'll show you how to use OpenDNS on your devices and how to configure them on your router, so that all devices connected to your WiFi or LAN network benefit from them.

What are DNS

DNS or better DNS servers are an important component for surfing the Internet, since they deal with translating IP addresses into URL addresses (and vice versa).

When you type a web address into your web browser (such as your browser contacts the DNS servers to "translate" this request into the IP address of the Google server closest to you. Eventually will become, which is one of the IP addresses assigned to the Google city server. You will not notice any thefference, but every time you browse a site the DNS servers are contacted to be able to route your request to the right server, so as not to "go wrong".

DNS servers are usually provided by the Internet service provider; then TIM, Infostrada, Fastweb, Vodafone etc. they have their own DNS servers for users who connect to the Internet through their services. If you have problems with your operator's DNS servers you can change them at any time and use other DNS services.

DNS servers are also used as a filtering system, in fact by blocking a certain type of DNS requests it is possible to make access to a site null, even by typing the URL address correctly. This method is used by your language providers to block access to pirated sites or sites restricted by the juthecial authorities; However, this blocking power is not present on foreign DNS services, which you can then use to circumvent this type of blocking.
