Substitute a different DNS server

I am on Verizon and the original DSN assigned through logging on is one of WesTell which does not work reliably.  I have switched it to a DNS that is on Verizon.

Here is a list of Domain Name Servers that was listed on LockerGnome:  http://help.lockergnome.com/lofiversion/index.php/t33278.html (bad link), also check out http://www.opennic.unrated.net/public_servers.html and http://www.thefreecountry.com/webmaster/freedns.shtml, A few dns numbers to keep in mind 198.6.1.5, 198.6.1.4 at uunet
 
A very good article on DNS servers is Operation timed out - MozillaZine Forums, which was referenced from another Firefox article Error loading websites - MozillaZine Knowledge Base.
 
Public DNS Servers

Of course you have to know where to place the information so that it can be used.  To see the JPG file you need to be in at least Full Screen mode, viewing the image with IrFanView or other image browser/editor would be even better.

   I thought I had set set a secondary DNS server but it looks like it
   was just set to     4.2.2.2     which is Verizon
   it probably had a  WesTell  DNS server before through code.  You can check with
IPCONFIG /all

Miscellanous Ramblings


Problems with DNS server,  you connect to some sites but not others
   see http://help.lockergnome.com/lofsolver/index.php/t33278.htm (dead link)
   it is best to have a primary and a secondary

   You should be able to get to   http://www.ibm.com  

   For trouble shooting you would be asked to go to Start  /  Command prompt
                        -- or from  Start / Run  /   cmd.exe
        ipconfig
        ipconfig /all

   to clear up and start again  (if computer was used elsewhere you might need to...)
       ipconfig   /release
       right click on the network icon if on you task bar (at bottom) and disable
       back to your   Network and Connections
       start your LAN  again.

If you have problems connecting,  call your  ISP  the help should be free.
Call from a wired phone with a speakerphone, it may be over half an
hour before you get through to a person.

Unqualified names

Check whether your computer's network settings have any DNS suffixes for resolution of unqualified names.

Assuming you are running Windows XP (browser prefix (www) and suffix (com) no longer added - mozilla.support.firefox)
3.1 Open Control Panel >> Network Connections
3.2 Double-click your network connection
3.3 Click the "Properties" button
3.4 Under "The connection uses the following items", select "Internet Protocol (TCP/IP)" from the list.
3.5 Click "Properties"
3.6 Click "Advanced"
3.7 Select the "DNS" tab
3.8 Under "Append these DNS suffixes (in order)", there is a list box for DNS suffixes.

Also see GRC site https://www.grc.com/dns/benchmark.htm
I used 4.2.2.6 4.2.2.1 and 4.2.2.2. If you only have room to enter two, that's OK. // Mark Lloyd in mozilla.support.firefox

Other things that could look like DNS problems

I would think the following might look like DNS problems:

IPCONFIG and PING (#ipconfig)

The following are done in the command window.
ping example.com   -- to find the ip address of example.com

with your connection disconnected
ipconfig /help
ipconfig /release    -- this and next one used sometimes 
ipconfig /refresh       when switching connections to another ISP (at another site)  
ipconfig /flushdns   -- haven't tried this
