so many top level domains.. I got on a support call recently and they said go to <vendorname>.support. I asked them to confirm as I expected something longer like <vendorname>.support.somethingelse.[some well known TLD]. But nope the actual TLD domain was .support.
I guess I must admit I have yet to encounter many of these TLDs in real world usage.
Per the .dev stuff I assume if people use .dev and host their own internal DNS they could override the behavior ? Provided of course the browser isn't sending DNS requests directly to the interwebs. I don't use Chrome nor do I use .dev so not sure, but am curious.
