Windows 10: Every PC Using and "automatically" Resetting a Loopback DNS

I am baffled by my PC loopback DNS scenario. I will be the first to state that this is totally new to me so I understand not a speck of it. I would deeply appreciate if anyone answering my post would PLEASE explain, beginning with the "basics".

I have more than 10 PC's in the household and of course I regularly use my Local network to transfer files. Every single one is running version 1909 (build 18363.xxx), Windows 10 Home or Windows 10 Pro. I somehow had the idea that if I set my own specific Preferred and Alternate DNS Server Addresses that I could cure what seems to be slow response most of the time. My plans were to use 1.1.1.1 as Preferred and 1.0.0.5 as Alternate. When I went to each PC to set my choices, I already found that each PC was setup to use 127.x.x.x as Preferred DNS (with no Alternate). I thought "aha" & "hmmm", but made my changes anyway. The settings didn't seem to make any speed difference so I went back into each PC to recheck my setup and then discovered that each PC had MY setting removed and each PC had reverted to 127.x.x.x. After a little searching I discovered that 127.x.x.x were all "loopback" DNS settings. I simply do not understand why this is being done and what is actually performing the nearly immediate reset.

I do have a KeePass password manager with a plugin and the password database then is synced via Microsoft OneDrive. Does this have something to do with what I now perceive as a "problem"?

Thank you very, very much!

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.

 

dns probe finished no internet


Hi Oxide,

After some trial-and-error testing of all suggested fixes, which I found over the internet, here’re what worked for me to solve "DNS Probe Finished No Internet" issue and might work for you as well.

Method 1: Change Default DNS Address to Open DNS

Here all you have to do is change your default automatically obtained DNS server addresses to open DNS or Google DNS. To do this, follow below mentioned steps:

Step 1: Right click on Network icon located in Windows Task Bar Menu.

Step 2: Click on ‘Open Network and Sharing Center.’





Step 3: Click on Local Area Connection with whom who are presently connected and click onProperties.

Step 4: Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click on Properties.

Step 5: Now in newly opened windows, select the radio button that reads ‘Use the following DNS server address:’

Step 6: Now in the ‘Preferred DNS Server’ box type in 208.67.222.222 and in ‘Alternate DNS Server’ type in 208.67.220.220.

Step 7: Now check the box that says ‘Validate settings upon exit’ and then click on OK. That’s it.
