The info you refer to is not about 2019 LTSC (at least LTSC is nowhere mentioned in the replies either), it's about non LTSC IoT Enterprise 1809 (EOS).
LTSC IoT 2021 is digital license only (IoT = Internet of Things, duh), meaning you have to have internet once to get a HWID activation (google MAS github) but then you can stay offline forever, unless you change hardware enough that the HWID changes which I don't know the exact condition when that happens, e.g. if it is motherboard, hard drive, NIC, etc. Regular LTSC 2021 has KMS activation available too which you can do completely offline with KMS_VL_ALL_AIO LTSC IoT 2021 has support until 2032 and regular LTSC until 2027 but they are identical with only license changing, you can easily change from one another using KMS_VL_ALL_AIO and MAS All these require the tools MAS and KMS_VL_ALL_AIO, you can't buy a key that doesn't require internet, every key you buy for all Windows after XP requires internet to get activated, the last time that a key activated windows without needing internet was the volume edition of XP Professional
first option i try is mephistoo2 kms suite 2. if kms suite fails then Kms VL All by abbodi 1406 work flawlessly.
For your purpose Hypercore or (Better) Azure Stack HCI are what you're looking for. Put the code, even if disconnected from internet, and you are activated. (see the end of the RDSH thread).
That key needs internet once to be activated, as I've said there is no completely offline option to buy, you need to use the activation tools
Who is that mephistoo2, what are you talking about? Always use abbodi1406's tool first, it's the most well known and open source option
I don't think so. That's what everyone is telling me. I'm all for data preservation and I'll keep activators on standby. But a legit key has it's uses too. Especially when you run a business.

Thing is... they are server core products, not regular client Windows and not even Server versions with GUI so not sure if they will suit you
I'm afraid you didn't understand a word of what I wrote, licensing (and activation) != product Not bad for being a no gui OS, isn't it ?
