Is it better to use my isp dns server or a public one like cloudflare? I’ve noticed that my isp dns servers are slightly faster according to ping tests but they fail the dnssec signature test, while cloudflare and Google dns pass all signature tests using dnssec standards. The difference in speeds isn’t really noticeable, but I’m wandering about security and privacy.
I use pi-hole resolving to opendns with Cloudflare as a secondary. I like the combined blocking impact of pi-hole and opendns.
