> This is a macOS bug; it doesn’t need an IP address while it’s asleep. Waking up to renew a DHCP lease is crazy.
It's actually not. As a user I'd expect the device to wake up and still have the same IP address via a continuation of the lease.
Yes, the correct way would be a longer lived DHCP lease, but el-cheapo ISP routers often lock down such settings.
Interesting, as a different user, I'd expect the opposite: If my computer is "asleep" I don't expect it to do anything, and it shouldn't be able to wake itself up.
The definition of waking itself up is unclear. Surely you expect clicking on your mouse or typing in the keyboard wakes it up? That means USB events or Bluetooth can wake your computer. Still it's user-triggered and doesn't count as waking itself up. And I expect that initiating an SSH connection to that computer causes it to wake up, because I initiated that SSH connection; so it doesn't count as waking itself up. I further configured my computer to back up to my NAS every day at midnight. Since I configured it myself I expect it to wake up on a timer and it still doesn't count as waking itself up.
that's called "off".
Turning a machine off loses any existing application state, and requires both applications and the OS to be re-launched.
When I put a machine into standby, I want it to go in a standby state, and then stay there until I explicitly wake it -- not keep doing whatever background tasks the OS developers, app developers, or whatever other third parties think they need to keep doing.

i suppose we have come to expect 4 states: - off: no power, no activity - hibernate: no power, no activity session state saved to non-volatile storage - sleep: Minimal power, RAM remains powered with the session state, can be resumed quickly - on
now we essentially have sleep++ and no option to set it back to vanilla sleep.

Most users don't know what IP addresses even are, let alone care what theirs is. I don't think Apple is (or should be) optimizing for you.
Okay, then… As a user I’d expect the device not to waste any time connecting to my wireless network and getting a dhcp lease, instead being already connected when I open the lid.
This is a good point (running processes might break if the IP address suddenly changed after wake-up). However, why should the renewal process take on the order of 15 minutes? And why would it require a complete wake up?
