Rapid DHCP: Or, how do Macs get on the network so fast?

The Mac's DHCP client is using the router's mac addresses to verify it's on the right network, and it already knows it still holds the lease. What the fuck more do you want? What are you afraid of?

The only conceivable grief you can put forward is that the ARP check isn't good enough. The client already owns the lease. If there's IP contention, it's because either a) it's not on the right network after all (arp check) or b) the server's fucked up and it's the servers fault (dhcp server allocated an IP twice).

Ok, so assuming the DHCP server isn't faulty may be a bit of a stretch. But coding your client to assume the server can do it's job does not deserve an "Ok, seriously?" hurf-burf post.

I take it you have not read any of the rest of this thread?... all of the comments about how DHCP in the wild doesn't work that perfectly, or people saying "this happens all the time with my / my wife/friend/boss's Mac"?
