This author has clearly never operated internal infrastructure at scale. The measures proposed in this are home lab grade at best, and require ludicrous levels of precision and overhead for something that changes thousands to tens of thousands of times per day.

And for very specific nit picks, and I can’t believe I’m entertaining this idea enough to ask, but tell me how the new device on the network bootstraps without DNS? And the guest device. And the printer without Ansible support. And the NDI receiver that needs to resolve its host. And how do you resolve split brain resolution for roaming devices? Are you going to publicly address all internal resources now so my laptop keeps working outside the office?

DNS was not created as a random solution looking for a problem…
