FAQ
What is the DNS Resolver Cache?
Whenever you visit a website using it’s domain name (i.e. microsoft.com), your browser is directed to a DNS server where it learns the IP address of that website. You are then directed to that website. A record of the IP address that domain name points to is created within Windows so that if you visit that same website again, the information is accessed quicker. These records that get created make up the DNS Resolver Cache.
Why would flushing the DNS Resolver Cache fix anything?
Sometimes an IP address to a site may change. If the DNS Resolver Cache has the old IP address record, it may result in your computer not being able to reach the site. Cached data can also become corrupt. Therefore, clearing it is a step you can take whenever you cannot connect to a site.
Can I view the data in the DNS Resolver Cache?
Yes. From a command prompt, you can use the “ipconfig /displaydns” command or the “Get”>-DnsClientCache” PowerShell command to view the data.

If you don’t want the command window to disappear, don’t use the Run command; use the Command Prompt command instead (as Administrator).
This will open a command terminal, wherein you can type
ipconfig /flushdns
and then to exit the command terminal window, either X at the top-right or enter the command
exit

To read the data, try copy and pasting everything into a doc. You can do this as the data is loading.
My question is about all the data that is in there after the flush. It appears to be junk but I’d like it gone so the next display dns is clean.

Ronald Kriel says
When using the run command “ipconfig /displaydns” the command prompt window scrolls by so fast I cannot read it. I did try “ipconfig /displaydns /p just in case it worked like directory searches. No luck.

Richard & Anika the ipconfig/flushdns window will appear and disappear quickly.. sometimes a momentary pause it the cache is rather full but otherwise sometimes you may not even witness it but it will function as per the command
