Basic introduction
Public DNS Server Tool is a small tool for dynamically changing DNS servers, available for Windows XP, Vista, Windows 7, Windows 8/8.1 and Windows 10.
Over the past few years, many public DNS servers have been made available for everyone to use. Some of them are Cloudflare DNS, OpenDNS, Google, Norton, Comodo Secure, etc. In addition to being incredibly fast, these DNS servers offer many layers of security and protection. Although these public DNS servers are available to everyone, setting up a DNS server in Windows is not an easy task. So I created this little Public DNS Server Tool that allows you to easily set up name servers in Windows.
Software features
You can use the Public DNS Server Tool to quickly switch to a preset pair of public DNS servers. Currently it has 16 preset DNS server pairs:
1. Google Public DNS
2. Cloudflare DNS
3.Verisign DNS
4.OpenDNS
5. OpenDNS FamilyShield (blocks websites not suitable for families)
6. Yandex Basic DNS
7. Yandex Safe DNS
8. Yandex Family DNS
9. Norton ConnectSafe A (blocks malicious websites)
10. Norton ConnectSafe B (blocks malicious websites + pornographic websites)
11. Norton ConnectSafe C (blocks malicious websites + pornographic websites + non-family websites)
12. Comodo Secure DNS (blocks malicious websites)
13. Neustar General
14. Neustar Threat Protection
15. Neustar Family Secure
16. Neustar Business Secure
Function introduction
Backup and restore:
Public DNS Server Tool allows you to back up your DNS server settings. To make a backup, select Backup → Backup from the menu bar and it will ask you where you want to save the backup file. The backup file will be automatically named with the current date and time in DD-MM-YYYY HH-MM-TT format. The backup file is in standard registry script (.REG) format, so you can restore the DNS server settings in the file simply by double-clicking it. It also allows you to restore DNS settings from the Public DNS Server Tool. To restore, select Backup → Restore from the menu bar. It will ask you to select a backup REG file. The entries within the REG file will be automatically inserted into the Windows registry. table, and the DNS server will be updated.
Set up public DNS servers:
1. Public DNS Server Tool requires administrator rights when running.
2. After running, first select Backup → Backup from the menu bar to back up your current DNS server. This is useful if you later want to restore the original DNS server.
3. Select your network card (NIC) from the network card drop-down list box. If you only have one network card, it will be preselected. When selecting a network card, the current DNS servers configured for the selected network card are displayed in large blue text. You can select the checkbox labeled "Select All" to select all network cards in the system.
4. Select a set of public DNS servers from the list. When you select a DNS server, their descriptions will appear below the list.
5. Finally click the Change button at the bottom of the window, this will take a few seconds to change the DNS servers. Even if you change your DNS servers, you can still view your browser with the previous DNS servers and then press Ctrl + F5 to reload the web page or restart your web browser.
Note that only the selected network card can change the DNS server settings. If you have multiple network cards, then you should choose the one you want to use to connect to the Internet. You can also select all network cards by checking the checkbox labeled "Select All." This way you can change the DNS servers for all your network cards with just one click.
Even after changing the DNS server, you can still browse the web in the browser using the previous DNS server and then close and restart the browser to browse using the new DNS server. If the changed DNS servers do not work after restarting the browser, you must restart Windows.
Add more DNS servers:
The Public DNS Server Tool, starting with version 2.1, stores all server data in the servers.ini file. When the Public DNS Server Tool is run, it automatically creates a default servers.ini file that contains eight well-known public DNS servers. If you want to add more DNS servers, you can edit this file to add more servers.
For example, let's say you want to add DNS servers from your own ISP (such as RoadRunner) whose primary DNS server is 24.25.227.55 and secondary DNS server is 24.25.227.53. Simply open the servers.ini file in Notepad and add the following at the end of the file:
[RoadRunner]
address=24.25.227.55, 24.25.227.53
Note that there cannot be a space between "address" and "=", otherwise it will not load. After adding you must close the Public DNS Server Tool and restart it before the newly added server can be loaded from the servers.ini file.
