Windows 10: after an unknown update, "ipconfig /all" don't show DNS

Hi after an update (I don't know which one), the command line command:

> ipconfig /all

Show no more the list of nameservers associated for every interface.

I think this is frustrating, like ads or bad changes that windows 10 usually brings.

p.s.: problem tested on multiple PCs.

So:

Are you suffering the same issue?

There is currently an alternative method to get DNS servers on cmd?

DNS unavailable

Hi Anthony,

Looks like you are experiencing connection issues due to your DNS servers not resolving the requests.

Let's perform these steps below to flush your DNS and request a new IP address from your ISP server:

• Press the Windows key + R key to launch the Run dialog box.
• In the run command type cmd.exe and click Ok.
• When the command prompt opens, type the following and press Enter after each command:
  • ipconfig /flushdns
  • ipconfig /release
  • ipconfig /renew

Kindly give us an update on how it goes and we will be glad to assist you further.

 

DNS lookups don't work in Windows except immediately after ipconfig /flushdns

If I run ping www.google.com in Windows 10 on a particular computer, it says
Ping request could not find host www.google.com. Please check the name and try again.

If I run ipconfig /flushdns and try it again right afterwards, it resolves the IP as expected and works as do other DNS lookups for a brief period of time.

I tried disabling the "DNS Client" Windows service but that didn't solve it (though restarting the service has the same effect as the above of things temporarily working).

I tried the network diagnostic tool as well as doing a full "network reset" via the windows settings screen.

Some possible items of note are

1. another computer connected to this network works fine
   
2. things used to be fine on this computer on this network and then they stopped working
   
3. pretty sure this computer works on another wifi network
   
4. running sfc /scannow doesn't detect any integrity violations
   

Here is some debugging output on the network that has the issue while it's occurring:

Here's the output of nslookup right after running ipconfig /flushdns:

 

DNS problems with router

A couple suggestions I have for you:

Update the firmware on the router. Maybe it's getting into a badstate, and a firmware update might fix it. Or if you're comfortable with it, install a custom firmware like dd-wrt. Just make sure its supported on your router first.

Change your DNS to: 8.8.8.8, 4.2.2.1. Might help.

If none of these work, maybe statically set your DNS on your PS3/PC to the IPs you listed, taking the router out of the lookup procedure.

Last option, is look for a new router.
