I just wanted you & others to know why I think they are bad. I support your choice to use them, if you want to.
X79animal: I sincerely hope you don't take this the wrong way. I use 4.2.2.1 & 4.2.2.2.easier to remember.&.non-existent domains FAIL, like they should. I could almost be OK with it, if I could opt-out without an account, for example have an alternate OpenDNS-without-Guide IPs to input instead of the main IPs. Yes, I know that if I create an account, I can check a box to turn this crap off, but I don't want an account & they should not do this anyway, let alone by default. I don't need their ad-ridden Guide to "help" me.but it's more than just their ads, it's the fact that EVERY DNS request succeeds, even for domains that don't exist.that's just WRONG. I will use Google, once I notice a domain don't exist. I also, do not want invalid domains to send me to their "Guide" to "help" me find what I was looking for. I DO NOT support DNS hijacking, if I wanna ping I want it to FAIL, not send a ping reply, as if that domain exists.
I tried them years ago, noticed the "Guide" (an ad-riddled page on "typo'd URLs"), then immediately switched back. Sure, it sounds "good".like "Open Source DNS"? But it is NOT GOOD. With CDNPerf, we will analyze Cloudflare, Fastly, AWS CloudFront, and Google CDN globally and over different continents. I keep wondering why soo many people like & keep recommending OpenDNS. The Pingdom test will analyze two of these CDN providers, Cloudflare and Fastly, using a small HTML page with the Pingdom page speed feature.
