Windows 10: DNS Cache

How do I find where the ip is stored in windows, where it keeps getting changed...... I can do a flush dns, and it will work for a while, but it always goes back to the old ip address....

 

Open an administrative command prompt and enter

Code: ipconfig /all[/quote] Please answer my questions in post #11.
Please also advise if you have any toolbars installed, what they are, and then uninstall them all.

The problem might or might not be on your end but rather, have you bothered checking the DNS Zone files for the domain to see what the Time to Live values are as it may not have expired yet or the serial number for the zone file was not increased so it's not updated on the Internet.

Use this for example and look at the IP returned as well as the TTL value:

Network Tools: DNS,IP,Email

and read this too:

Nslookup - Checking DNS Records on Windows | Knowledge Center | Rackspace Hosting

What you should do first is:
Open up a command prompt and do nslookup <domainname> like nslookup XYZ (@xyz) | Twitter and see if it is returning the old or new IP. Then do the above if it's returning the old IP to confirm the internet sees it the same way. Seems everyone on this thread thinks it is related to Windows when the above should be done first, then only when the internet sees it correctly and it's only wrong on your machine, that is the only time when you should even try to figure out what is causing it on your side.

 

You might want to try reset Edge, even though you are not using it.

Then please open Ccleaner and go to Tools on the left, then Startup, then the Scheduled Tasks tab.
Post a screenshot here or save to text file (bottom-right corner).

You have uninstalled all toolbars right?

 

I think we need to hold out on giving the remedy until we know it's a problem on the computer because unless the DNS domain name shows on the internet to be correct, then it could actually be someone on the Master DNS forgetting to increase the serial number so that the secondary DNS and the rest of the internet updates and then there is the TTL as in Time to Live Variable which is in the zone files.

 

Not pertinent to your issue, but be cautious posting things like that. It has your MAC address displayed.

 

Good point!

 

I did see something in the nettools page........ 2016-01-16_0934 - JimKSchwyz's library

I am on a reseller hosting package with namecheap........ and only having my sites on this server.... I will have to contact namecheap to see if it is possible for all of these ips to be on an ip that is assigned to my server... I have installed the anti-exploit yesterday, but it has not blocked anything yet.
thanks

Looks like the TTL is 20 minutes which means after 20 minutes, the DNS cache is supposed to automatically request the information but that is not always the case, I tried going to tshirtsbyjames.com which redirected to Tshirts By James | Great Designs Better Prices and it's working fine.

The only thing is it can be this problem which I learned about 16 years ago which you might find interesting and may be related since Microsoft uses a TCP/IP stack that is based on the BSD (Berkeley Software Distribution) stack but who knows if they had fixed this problem:
