DHCP Request

[LuckyLuke]

Hi,
there are 4 steps in DHCP: Discover, Offer, Request and Acknowledge. Why is the third step called "Request"? No one is requesting anything at this step, are they? The client simply is saying that it will accept the IP given by the DHCP server. Where is the "request" portion at this step?

[Spoiler]

The request is used because some networks have more than one DHCP server. The request picks a server to get the IP lease.

Thank you very much for your reply.

Reading the link you posted, it looks like the "request" is referring to the client requesting a lease from the server. Is that correct?

Yes that is right.
