In FireFox 3.5 at work, I can type "sears" in the FireFox address bar,
which takes me to sears.com. I'm not sure how to check what the DNS
server is since the company is big, or even if the DNS is the factor
here.

At home, I use Google DNS (8.8.8.8, 8.8.4.4). When I type "sears"
into the FireFox 3.5 address bar, I'm taken to this page:
http://guide.opendns.com/?url=sears&client=ff

Does this mean that Google is using OpenDNS somehow? I've checked
FireFox and I don't think the problem is coming from there.

Please advise.

For work: What's probably happening is that Firefox sees a URL
"http://sears/" and tries to resolve "sears". Upon discovering there's
no such host, Firefox probably tries to resolve "www.sears.com", which
succeeds. Redirection is happening, but on the client side in your
browser, which you can more readily control.

For home: Google Public DNS should work the same way. It certainly
should not direct you to
"http://guide.opendns.com/?url=sears&client=ff". (And even if it did,
that should quickly redirect you to "www.sears.com". It did for me.)

Maybe somehow you're still using OpenDNS? If you go to
"http://welcome.opendns.com/", are you brought to a page that tells
you you're using OpenDNS, or to a page
("http://www.opendns.com/welcome/oops/") that says, "You aren't using
OpenDNS yet"?

Hope this helps. --PSRC

P.S.: Yes, it would be helpful if there was a test that could tell
you, "Yes, you are using Google Public DNS."

And even if you've stopped using openDNS, it may take a couple of days
before that "takes". It did for me.

the test is to go to a command window and type

nslookup www.google.com (or some other url)

it will show the follow results:

nslookup www.google.com
Server: google-public-dns-a.google.com
Address: 8.8.8.8

Non-authoritative answer:
Name: www.l.google.com
Addresses: 74.125.95.105
74.125.95.103
74.125.95.99
74.125.95.106
74.125.95.147
74.125.95.104
Aliases: www.google.com

You may want to clear your DNS cache, and if you changed the DNS
settings in your router, it may be necessary to refresh your DHCP
settings on the computer.:

Open a command prompt (As Administrator for Vista/7)
ipconfig /flushdns
ipconfig /release
ipconfig /renew
