Most people have never heard of
Now, as humans, we simply cannot remember the IP addresses of every website and device we use on a daily basis. Enter the Name Server. The Domain Name Server is like a huge telephone book that lists the IP address of each website and device on the internet. So, to visit google.com, your computer browser asks your Internet Service Provider for the IP address. Since most ISPs don’t cache their DNS lookups, they have to send the request on to an “authoritative” name server for that domain. The authoritative server will return the IP address to your ISP, and in turn, the ISP will
GoDaddy has sold the most domain names and offers a free name server service. When their name servers went offline, there was no “authoritative” answer available and the requests just failed.

In addition, OpenDNS provides various levels of protection at the DNS level. So, if OpenDNS knows that the site you are about to visit contains a horrible virus, it can intervene and redirect you to a safe page with an explanation. Parents and business owners can also use built-in tools to limit access to websites that contain content such as pornography, gambling, social media, and many other categories. Not only does this help parents manage the sites their kids see, but it also helps businesses keep content that is offensive from their employees that might result in legal action.
Additional tools such as analytics let you see which sites your family or business are visiting and will also list potential malware and virus threats. The system can even alert you when a machine on your network is acting suspiciously and trying to access known malware servers and services.
Utilizing a third-party service such as this can allow a small business to have access to the same features and tools enterprises have had for years. They are able to utilize an additional layer of security and redundancy for a very small cost. And, for concerned parents, we are able to monitor the internet usage from our homes and ensure that our children are not able to access content we feel is harmful.
