I mean generally above a certain size of deployment DHCP is much more trouble then it's worth.

DHCP is really only worth it when your hosts are truly dynamic (i.e. not controlled by you). Otherwise it's a lot easier to handle IP allocation as part of the asset lifecycle process.

Heck even my house IoT network is all static IPs because at the small scale it's much more robust to not depend on my home router for address assignment - replacing a smart bulb is a big enough event, so DHCP is solely for bootstrapping in that case.

At the enterprise level unpacking a server and recording the asset IDs etc is the time to assign IP addresses.
