I assume MacOS actually only re-uses IPs if it sees the lease hasn't already expired but it might be dumber than that.
- lloeki 4y agoIIRC it does, and otherwise throws out (or used to) an ARP check (or something like that) to see if any one on the local link is using the IP. A properly behaved DHCP server would not hand the IP again to someone else if the lease hasn't expired.
- nielsole 4y ago> properly behaved DHCP server One of the common issues with this is that home routers don't usually persist leases across power cycles.
- Fnoord 4y agoIIRC DHCP leases should be refreshed at their half-time. Or perhaps I am mistaken and this is how Windows works.
