Configuring the default DNS Server addresses

  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

The following may be helpful if you are not a DNS guru and are experimenting with DNSBench.

The DNS Sever addresses can be set in three ways in Windows. IPv6 is only applicable if it is a supported protocol by your ISP. If they are not set then the default will be the DNS defaults set by your ISP.

1. Router: configure in a self managed router. This is normally not possible with an ISP managed router as these settings are hidden or disabled.

2. PC Adapter (Windows): Control Panel>> Network and Internet>> View Network status and task>> Change adapter settings>> Wi-Fi>> Activity-Properties>> Internet Protocol Version 4 & 6>> Properties>>, Use the following DNS addresses (Preferred and Alternate)

3. System (Windows 11): Settings>> Network and internet>> (Wi-Fi or Ethernet) Properties>> DNS server assignment - Edit>> configure IPv4 and IPv6
Note separate configurations are possible for Wi-Fi and Ethernet, and for each Wi-Fi network

Item #2 overrides #1, and item #3 overrides #2.

If #2 changed after #3 is configured it will override #3.

Note 1: DNS over HTTPS can be set to automatic with #3.
Note 2: It is safest to reboot after any changes to #1 and #2.

To copy the listed faster DNS servers from a DNSBench 2
[ Conclusions ] tab after a Benchmark:
  1. left-mouse-click-and-hold, and highlight the list,
  2. right-click, select [ Save Text selection to File ],
  3. in File Explorer, at Save as Type:, select [ Plain text file (*.txt) ],
  4. in File Explorer at File Name: type firstname.INI, select [ Save ],
  5. then open the INI file in any text editor and replace all spaces with nothing.
Because leading spaces cause DNSBench to ignore the line when
importing an INI file.

Alternatively, after a Benchmark:
  1. save a CSV file,
  2. open it in any CSV editor,
  3. sort by the [ Average Average ] column ( or whatever performance we value ),
  4. highlight as many DNS Servers in the [ Server Address ] column,
  5. down to, I suppose, our own first System DNS Server in the column,
  6. then copy and paste that into any text editor,
  7. and save as an INI file.
- - - - -

To "... copy the 50 best DNS servers to the .ini file ..."
after Build Custom List,

it will auto-save as {ProgramName}.INI, if available,​
( caution, DNSBench does not make a backup of any previous​
{ProgramName}.INI file ),​
and or we can select File > Save DNS servers to .INI file​
( or whatever equivalent wording is in the version of​
DNSBench in use ).​

Does that work for anyone?

I document 13 places that your DNS configuration may come from. And I do not claim to be an expert. That's why its useful to test your DNS to see that you are using what you expect to use. See some testers here
