[OT] Free DNS Servers

[Chris Dubea]

Greetings all.

This is not software related, but I need some assistance.

I use a WiFi connection at work on my laptop to access the "real
world" and lately the DNS servers have become unreliable. I've sent
the IT nazi several messages about it, but as I'm the only one here
experiencing the problem, the motivation to solve the puzzle is
minimal.

Is there a free DNS server out there that I could hardcode to my
TCP/IP connection? Hopefully this would alleviate the problem.

Thanks in advance,

===========================================================================

4.2.2.2 is an easy IP to remember if you need DNS.

Excellent. Thanks. I'll give it a try next time our DNS server burps.

As you're the only one experiencing the problem at your workplace,
might the problem then not be at your computer?

Like your computer secretly connecting to a DSN server that that
redirects you to somewhere else as to the site you where expecting to
go to?

Example: you want to go to google.com, and altoiugh the adress bar of
your browser says google,com, you get somewhere totally different.

Just an idea... Cause if the DNS servers at your workplace where
unreliable, others should expreience the same problem too.

Also look for a file with name HOSTS on your computer, the file might
be hidden, can be viewed with a text editor.

The only connection point that I can tell which is having problems is
the WiFi connection that is in place to allow customers internet
connectivity. I suspect I am the only one using it at this juncture.
The exact same configuration works fine with my home wireless (which
uses the same router as the one at work).

The servers as such aren't unreliable. When I connect with my laptop,
the linksys wireless router provides an address something like
10.3.2.XXX. The proper DNS server is at 10.3.2.2. For whatever
reason, more often than not lately the DNS server will come up as
172.16.1.XXX (which is the DNS server for the wired network). I
suspect the 172.16.1.XXX server is firewalled off for security.
Occasionally it will fire up with the correct DNS server and then reset
itself to the 172 server. I've tried hardcoding the DNS server to
10.3.2.2 but that doesn't work either.

Which is all why I was looking for publicly available DNS servers.
It's the easy answer as our IT person won't even respond to my e-mail.

Cheers,

It's also on another segment, so you can't really access it.

itself to the 172 server. I've tried hardcoding the DNS server to

Do you have "Obtain an IP address automatically" checked? (Probably,
if you have to select a hard coded DNS address.) Does the router at
work have its DHCP server turned on? (From what you said, probably.)
Just throwing out ideas.

And you're certain you're not connecting to some other wireless
network, right? (I can connect to 3 of them from my office.)

I see. At first glance it looked like your dns connection might had
been hi-jacked by some malware, or that your HOST file was
compromised.

And what if you use a static ip adres for the laptop, provide ip adres
for deafault gateway and dns?

Sorry to hear that your IT department sucks...

Well, hope you get it working, 1 way or the other.

Yes the network connection is correct. We have WEP encoding and it's
the only system I have setup. I can move my computer to the other side
of the office and the problem goes away ;>

I e-mailed the IT girl about this and bing! The light goes on. She
moved the router that was in my end of the building upstairs last week.
She will return it to it's previous location tomorrow.

Thanks to all who answered. This one has been a real mystery.

You didn't give us that information... = ;-)
