Whenever a domain name is typed you are taken to that particular site. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address which is very hard-to-remember. This process will be carried out by various DNS (Domain Name System) servers around the world .
While this conversion occurs in the background it is vital for your Internet speeds.The communication between user’s computer and the DNS server is carried out by your browser which acts as a DNS client. Yet, despite being largely transparent, the DNS system is not without its problems.
If your ISP’s DNS server is down then you can’t access that website unless you know its ip address.So instead of relying on our ISP’s DNS server we can switch over to Open DNS , a more reliable and a secure service.
OpenDNS
OpenDNS is a free DNS resolution service. OpenDNS offers DNS resolution for consumers and businesses as an alternative to using their Internet service provider’s DNS servers. By placing company servers in strategic locations and employing a large cache of the domain names, OpenDNS usually processes queries much more quickly, thereby increasing page retrieval speed.
