I am using 140 ESR version on linux with Cloudflare's DNS over HTTPS and with DOH active for some reason resolving a domain like d3oklwo3y1bx83.cloudfront.net will resolve to local host IP 127.0.0.1.

I am using firefox about:networking#dnslookuptool to test resolution of the domain d3oklwo3y1bx83.cloudfront.net Both with DOH on and off the resolution remains local host. I tried another browser on the same workstation and I was able to receive a resolution of 13.225.193.203 13.225.193.133 13.225.193.64 13.225.193.58 Why is firefox ESR not able to resolve that domain? What are causes ?

Is is firefox dnslookuptool results.

I have DoH set to Increased Protection using Cloudflare and when I do a DNS Lookup at about:networking#dnslookuptool I got the following back:

IPs 52.222.157.111 52.222.157.127 52.222.157.189 52.222.157.6 HTTPS RRs 1 d3oklwo3y1bx83.cloudfront.net (alpn="h2,h3" )

I am on Firefox release 147.0.3. So, seems like it should be working.

Thanks for the confirmation. However when I use DNSlookup today 3-march-2026 I get a different value.

IPs 3.168.117.220 3.168.117.227 3.168.117.34 3.168.117.160 HTTP RRs 1 d3oklwo3y1bx83.cloudfront.net (alpn="h2,h3" )
