Improve security and speed with alternate DNS servers, A simple configuration change can make a huge difference (and it’s free)

Did you know that you can improve both your Internet browsing performance and security by choosing an alternative DNS resolver? The good news is that it’s free and only takes a minute of your time to make the switch to another provider.

What is a DNS probe?

The Domain Name System (DNS) can easily throw off the language of your nearest network administrator, but the average user probably doesn’t know or care what DNS is or what it does for them.

DNS is the glue that binds domain names and IP addresses together. If you own a server and want to allow people to reach it using a domain name, then you can pay a fee and register your unique domain name (if available) with an Internet Registrar like GoDaddy.com or another provider. Once you have a domain name linked to your server’s IP address, then people can reach your website using the domain name instead of having to type in an IP address. DNS “resolving” servers help make this happen.

A DNS resolver allows a computer (or a person) to look up a domain name (eg) and find the IP address of the computer, server, or another device it belongs to (eg 207.241.148.80). Think of a DNS resolver as a phone book for computers.

When you type a website’s domain name into your web browser, behind the scenes the DNS resolution server your computer points to works to look up other DNS servers to determine the IP address that the domain name “resolves” so that the program your browser can go and retrieve whatever you browse on that website. DNS is also used to help find out which mail server a message is to be delivered to. It has many other purposes as well.

What is DNS Adjuster?

Most home users use whatever DNS resolver is assigned to them by their Internet Service Provider (ISP). This is usually assigned automatically when you set up your cable / DSL modem or when your wireless/wired Internet router automatically goes to your ISP’s DHCP server and grabs an IP address to use on your network.

You can usually find out which DNS resolver is assigned to you by going to your router’s “WAN” connection page and looking under the “DNS Servers” section. There are usually two, a primary and an alternate. These DNS servers may or may not be hosted by your ISP.

You can also see which DNS server your computer is using by opening a command prompt and typing ” NSlookup ” and pressing enter. You should see a “Default DNS Server” name and IP address.

Why would I want to use an alternate DNS resolver other than the one provided by my ISP?

Your ISP may do a great job of how they set up DNS servers to resolve issues, and they may or may not be completely secure. They can have tons of resources and terrible hardware in their DNS resolvers, so you might get super-fast response times, or you might not.

You may want to consider switching from your ISP-provided DNS resolvers to an alternative solution for a number of reasons:
