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

DNS (Domain Name System) exists to help us access resources online. It is a collection of network servers that translate Internet hostnames (e.g. www.google.ca) to IP addresses (e.g. IP addresses are what computers use to communicate with each other, but people prefer meaningful names. We would much rather type http://www.execulink.ca than

Execulink employs two DNS servers for our customers: and Using these DNS servers ensures minimal delay each time a hostname to IP address conversion takes place.

How do I know what our settings are?

To find your DNS servers on a Windows 7 computer:

1. Click on the Start menu.
2. Type cmd in the Search Programs and Files field, and then press Enter.
3. Type ipconfig /alland hit Enter. If you see and in the results, you already have the correct DNS servers configured.

If not, continue reading.

You will need to determine how your DNS servers are being assigned, either manually on the local computer or automatically by a DHCP (Dynamic Host Control Protocol) server or router. Check the results of ipconfig /all again. Do you see 'Yes' or 'No' next to DHCP Enabled?

No: DNS information is likely assigned manually on the local computer.
Yes:Your DNS information is being assigned by a DHCP server or your router.

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

Execulink strongly encourages you to obtain your DNS server information automatically whenever possible, as this makes managing multiple devices easier.

Instructions for assigning DNS servers in Windows:

Windows XP
Windows Vista
Windows 7

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

There are many possible answers to this question, due to differences in server and router configurations. However, you can determine which device is acting as your DHCP server by reviewing the information in ipconfig /all.  If DHCP Enabled were set to yes, you should see another line that reads, ‘DHCP Server.’ The IP address shown here refers to the device that is assigning your DNS servers.

Please contact the person who manages this device for you, or the device manufacturer for further assistance.
