Enter the records (or import) at … Read More “Migrating domains to new registrar with DNS entries” »

I’ve noticed that about 10% of their order receipt emails are not being delivered, getting denied.

However, I would like it to also enforce safe mode/search on YouTube and search engines like Brave search. … Read More “Best Public DNS for Parental Control/Blocking porn” »

Hi everyone, Is there a tool in order for me to test if my DNS setup correctly block known malware, botnet and other malicious stuff?

I have had AdGuard Home running for 2-3 years now as an internal ad blocker and DNS server, becoming public DNS 12 or so months ago. It’s been smooth sailing with about 1 million queries per week from the known or justified clients until today.
