How DHCP works?

Short answer. Just four steps.

1. DHCP discovery. The client sends a broadcast packet to tell DHCP server that it wants to get an IP address.
2. DHCP offer. The DHCP server receives the packet from client. so it also sends a broadcast packet to tell the client that I can offer an IP address.
3. DHCP request. When the client receives the offer packet from DHCP server, so it sends a request to DHCP server to get IP address.
4. DHCP acknowledge. The DHCP server gives the IP address to client and lease time.
