🙂 It's only Discord, we're all here to have a good time, and this was fun. I just started a meeting at work, so I have to disappear anyway. Cheers!

Could you try
dig @1.1.1.1 48773.NET
This is a random domain I found that was just created
Creation Date: 2025-01-06T08:53:08Z
Domain Status: addPeriod
And has the status, this would rule in/out my hypothesis of filtering at an ISP level using that one ICANN tag95 replies

Are you in the US or what country are you from? And have you ever noticed anything that would indicate a MITM or DNS poisoning beyond this?

Right. It's just in comparing what you and I can see, and it working over DoH (and also the exact same domain) not working from his PC (different machine) but other domains do work.
That's the only thing that stands out is how new the domain is

Ohhh, Radar, I hadn't considered that. I just know think that ICANN flag falls off after 5 days

I mean, it works over DoH; filtering is being done somewhere...

haha, I'm not sure. I only say it because it could just be a simple way to defeat Command and Control servers? But it's a stab in the dark. Proof would be after 5 days, is when that flag falls off, I think.

I'll make this one last observation and seriously leave you alone hah, and I'll follow this, because I'm super interested now.
I don't know if ISPs filter for "new domains"; but in the email realm, filtering can be used to protect against "brand new domains".
Your domain has a tag (that is not service impacting and is only informational) ... but, maybe your ISP uses it for their filtering and will work after this tag falls off.
Domain Status: addperiod https://icann.org/epp#addperiod
This is 1000% a shot in the dark. I just can't move passed 2 machines on your network & only this domain.95 replies

Also, are you doing anything fancy with your vlans, like outbound traffic routed through a vpn?

telnet 1.1.1.1 53
I assume that connection timeout? What network gear are you using?I can't get past these two points 1) Your desktop also can't dig this. 2) Other domains in a dig from the same machines work (just this single domain). So, my pretend-network advice would say 1) Rules on your network gear 2) Something unique with filtering or that vlan or that vm isn't on the vlan you think 3) Your ISP is doing some type of filtering (for that one domain -- which, I couldn't imagine).

The reason I ask is because some non-standard ISPs do CGNAT. I was kinda of thinking routing.

I'm intrigued now, lol. The VM, did you use like an iso or a build you had before and/or did you do any super specific customization? Just thinking outloud. If you get it answered/fixed on another discord will you reply here just so I know

This would rule out dns cache, which is still a possibility if it's only this new domain v. every dns request
