DNS FAQ

What is DNS, and what does this have to do with me?

DNS or the Domain Name System is a collection of network servers (computers) that translate internet addresses (like www.google.ca) into IP addresses (numbers like 74.125.226.56 which are assigned to devices connected to the internet). "DNS Servers" perform this translation.  IP addresses (numbers) are what computers online use to communicate with each other, but for us humans meaningful names are needed (www.execulink.ca not 73.194.43.119).  This is why the DNS system exists.

At present time, Execulink employs several DNS servers. Two of these DNS servers are intended to be used for your DNS queries as our customer, 199.166.6.2 and 209.239.11.98. Using these DNS servers will ensure minimal delay each time one of your customers needs to translate a hostname to an IP address for you.

How do I know what our settings are?

To find your DNS servers on a Windows computer:

  1. Click on the Start menu.
  2. Click Run.
  3. Type in cmd, and hit enter.
  4. Type in ipconfig /all and hit enter. Your DNS servers should be listed there.

If these show, 199.166.6.2 and 209.239.11.98, then you have the correct DNS servers assigned and you are good to go.

If not, continue reading. You will need to determine next where your DNS servers are assigned from, either manually assigned on the local computer, or they may be automatically assigned from a DHCP server like your router. We can find out by reviewing the output from "ipconfig /all" that we did earlier.

Look for DHCP Enabled. If it says no, your DNS information is likely assigned manually on the local computer. If it says yes, your DNS information is being assigned by a DHCP server like your router.

My DNS servers are assigned manually, how do I change them?

Execulink encourages you to obtain your DNS server information automatically whenever possible, as this means fewer devices that you need to apply changes to in the future.

Instructions for assigning DNS on Windows XP can be found at: http://support.microsoft.com/kb/305553 Follow the section "How to configure TCP/IP", steps 1-5

Instructions for assigning DNS on Windows 7 can be found at (Vista instructions will be similar): http://windows.microsoft.com/en-US/windows7/Change-TCP-IP-settings Follow the steps 1-3, and 6.

My DNS servers are assigned automatically by DHCP, how do I change them?

There is no generic step-by-step answer for this, as there are too manyvariations of routers and servers that you may be using as a DHCP server.

At the very least, however, you can determine which device is acting as your DHCP server by reviewing the information in ipconfig /all.  If DHCP Enabled was set to yes, you should see further down another line that reads DHCP Server.  The IP address that is shown here refers to the device that is acting as your DHCP server.

Please contact the person who manages this device for you, or the device manufacturer for further assistance in ensuring you have the right DNS servers assigned.
