I've changed my DNS resolver to Quad9 in Firefox (dns.quad9.net), but a test on https://www.dnsleaktest.com/ shows that I'm still using my ISP's DNS resolver!
What could be wrong? 🤔
@frankie So using a generic DNS provider and being concerned about DNS leaks? Do you even privacy
a) Tor DNS (A and AAAA only)
b) bind9 - So that you avoid the middle party and fetch the data directly from the root servers
