Does Cloudflare dns 1.1.1.2 do a pretty decent job at blocking some malware domains as compared to the regular 1.1.1.1? I know Quad9 is supposed to be good at this but it’s much slower at my location. submitted by /u/kdbtiger [link] [comments] Powered by WPeMatico

Nothing like debugging “Private DNS not working” for half the day, only to find you fat-fingered 1dot1dot1dot1 instead of 1.1.1.1. Meanwhile, normies out here raw-dogging their ISP DNS like it’s 1997. Stay vigilant, my resolver warriors. submitted by /u/specagop [link] [comments] Powered by WPeMatico
