Before I show you how to do this, we have a brief explanation of what Domain Name System is. Think of the task of a phone book - it allows you to name someone to look up their phone number. DNS also has such a task, except computers: if you type 'google.com', it will translate that name into a four-digit string, this number is called an IP address, in this case with google.com is 72.14.207.99.

Overall, Internet infrastructure includes a lot of phone books, or DNS root servers, located at strategic points around the world and maintained by a variety of private, semi-public or public providers. plus. They communicate with each other according to the basic principles; to ensure that when we add new domains they will be synchronized. As you can imagine, if someone wants to poison one of these entries or mislead Internet traffic to a fake domain, it can be done with a number of hidden behaviors. That's what happened last year when an Internet service provider in Pakistan blocked access to all of YouTube's networks when they wanted to show a page of offensive videos to Pakistani netizens.

This is where OpenDNS comes into play. When you set up your network, often you won't think much about your DNS settings. If you use a cable or DSL modem, you connect it and it will automatically retrieve the default DNS settings from the cable or DNS company DNS server.

What you need to do to be safe here is that you need to change these settings to reflect NDS servers at OpenDNS. This is a free service and you may be wondering about how to maintain it, the service will charge money for advertising when you type into a non-existent domain. There are specific instructions on this website based on each router you use on your network and the whole process doesn't take you too much time to read and make changes.

There are some interesting things while using OpenDNS. First, you can set up lock for certain object domains, so you can protect yourself about litigation. It also takes time to block domains, so you can avoid trapping by some hackers. Besides, you also get better DNS services because they have responsive servers faster than general Internet domains. Also avoid spelling errors in domains, so if you make a mistake in typing names in the browser, they can direct you to the location you intended.

OpenDNS is opening a security solution for your DNS resources. Hope this service will be interested and promoted its advantages.
