A DNS, also called a nameserver, is like the phone book of the Internet.
If you're a longtime reader, you've probably heard the term before. Every computer and mobile gadget has an IP address.
This is what identifies it to other computers, and website servers are no different.
When you sign up for Internet, your provider assigns you to its DNS server. It could be bogged down with traffic, running inefficient software or any number of other problems.
If your computer can't look up IP addresses quickly, it seriously slows down your browsing.
This will automatically be filled with the IP address of your current DNS. One says "Include global DNS providers," the other says "Include best available regional DNS services." Leave both of these checked. The first checkbox lets you check if the DNS is blocking certain sites.
If you're looking for a DNS with filtering options, definitely select this one.
Many DNS systems include filtering to block inappropriate websites or other sites you don't want to see.
Open DNS is one of our regular recommendations for filtering.
