Re: the DHCP client attempts to re-use the last good IP address
Really? I can't find a reference to this. Is it part of some wake-up protocol? My initial comment was based on trying to crowbar the OPs highly stylised and anthropomorphic version of DHCP transactions into the agreed way to describe the sequence of events. "Can I use x address?" I interpreted as a REQUEST without it being in response to an OFFER following a DISCOVER. That shouldn't happen, so I thought maybe they meant DHCP RENEW. Which, quite rightly does contain the client IP address, but is more of a "Can I continue to use?"
