Configuring your DNS Servers Part 1.


My next two posts will help you to configure your computer (or router/modem) to use DNS servers that are different than your ISP provides.  As mentioned in my previous post on Google Public DNS, there are reasons why you may want to choose a public or “open DNS” server over your ISP’s servers.  Or you may want to install one on your computer or network.

First things first though:

If you’re considering installing your own DNS, there are two that I recommend highly.  The first is the BIND DNS Server that you can find here.  This is the basis for a lot of DNS Servers (including the ones that are present in most *nix systems).  The second is called TreeWalk DNS (which is based on BIND), and can be found here.

Both of these will configure the computer that you install them on, to use them instead of your ISP provided servers.

Ok, so you don’t want to deal with DNS yourself, but want to use Google Public DNS or OpenDNS.  In this post, I will give you some of the information needed to get started, and the next post will have the steps (based upon the steps provided by Google) for configuring your DNS.  I will break it down into “On your computer(s)”—which will be broken down into “Widows based”, “Mac OS-X based”, and “Linux based”, and “On your router or modem”—which will be generic instructions (since the steps will vary widely).

So, with that, here we go:

The IP addresses for the DNS Servers are as follows…  You do not need all of these, nor do you even need to put both of them in (for each provider).  In fact, you can use one from each provider, if you wish.  However, you cannot use the same IP address for both Primary and Secondary DNS Servers.

Google Public DNS:  8.8.8.8 and 8.8.4.4 are the IP addresses that you’ll choose from.  You’ll put one in the Primary and one in the Secondary (if you choose to do so).

OpenDNS:  208.67.222.222 and 208.67.220.220 are the IP addresses that you’ll choose from.  Like Google’s, you will put one in the Primary and one in the Secondary.  And it doesn’t matter which one is first or second.

In my next post, I will go through the actual configuration steps for you.

Have a great day:)
Patrick.
