> It's kind of wild how many things don't fall back to IPv4 quickly (lots of Android TV apps) or at all (.NET). I tried reaching out to Spectrum support, but being a lowly consumer I was only told that "The modem doesn't have any filters" and that "the problem may be on the CloudFlare side", which was sadly what I predicted. So, I figured I would raise the issue here in the hopes that actual network people would see it.<br>
