Useful tool to update your DNS to block ads, trackers, malwares domains.
We recommend Adguard DNS
94.140.14.14
94.140.15.25
We also recommend you to install Adblock Plus in your browser (Firefox, Chrome…) so that you surf the net without annoyance.
At the bottom of the sidebar on the right there is a link to "Google Translate". You can click on it and then choose your language.
There is also now a translation option in browsers such as Chrome, Firefox, etc.
Is there any convincable reason, why you don’t follow international standards and exclude the whole NON-ANGLO world from translation of your website?
Leastways french, portuguese, spanish, chinese, japanese, korean, russian, indonesian and german should be available in the top area of your website, like million others do it.
That is annoyingly pretty backwards.
hey sorry for replying so late, but i do have comodo firewall installed, and windows defender of course. I’ve tried disabling all of them, but still nothing.
I’m on Windows 11 23h2 22631.2861
The weird thing is, it was working fine on windows 10.
Dns Lock is set up as a service and the service checks the Dns address at intervals.
If the Dns address has changed, the Dns specified in the installation will be reassigned.
If you get an error that the service could not be installed, your security software may be blocking it.
What system and security software are you using?
I get "service could not be installed" What gives?
We have Noted it down , Thanks
join apps:
maybe you can "join" this app great feature to dnsjumper. so we have dnsjumper with dns lock based on dns jumper configuration.
example. i set every 60m test and pply fastest dns. then after apply, the DNSJUMPER will lock that dns until unlocked or processed by dns jumper command
Works very well
Static ip is related to your internet service provider, nothing can be done about it.
Is it possible to make the same program but for IP addresses?
Thanks in advance.
Please Make a App For Dns Cleaner
Hi , we have noted it down , thanks for your comment.
Any chance of adding the option to password protect the program? I’d be willing to pay some money for that.
The program changes the dns on all available network adapters (network cards, etc.). So it doesn’t matter if you have more than one
Dose not seem to protect multiple Ethernet cards. I have one for internet and another one for internal both have different ip4 dns.
