alt Hacker News> 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.

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.
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?
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.
