Originally reported @ https://github.com/webcompat/web-bugs/issues/55690
STR:
- In Fenix (or Fennec...) try to load http://punjab.indiaresults.com/pseb/default.htm
Expected: it works
Actual: "Address Not Found"
This page loads without issue in Desktop, and AFAICT we're served the same page from the server.
I get "address not found" on desktop nightly
Performing a lookup for punjab.indiaresults.com
in about:networking
also results in unknown host.
I get the following resolver logs:

(In reply to James Willcox (:snorp) (jwillcox@mozilla.com) (he/him) from comment #1)
I get "address not found" on desktop nightly
Ah whoops, I guess I only tested in DevEdition. >_>
edit: no, at least on macOS, the lookup succeeds on the latest Nightly for me.

I cannot reproduce it on Fennec. Valentin, can you please have a look at it?
I can't reproduce on either desktop or mobile.
The result seems to come from the DNS resolver, so I'm assuming the domain is either intentionally or mistakenly blocked.
It could also be caused by something like bug 1184059 that only manifests on mobile, but considering comment 1 I assume that's not the case.
James, can you still reproduce this? Could you let me know about what resolver you're using? https://whatismyresolver.com/
Also can you check if the domain can be resolved in the terminal? dig punjab.indiaresults.com
and dig punjab.indiaresults.com @1.1.1.1
I can't reproduce this anymore. It seems to be resolving without issue now. When I was able to repro, dig
was returning results just fine. I guess we can close? Pretty strange...
Let's hope it was just an temporary DNS configuration/propagation issue.
