How do DHCP servers work?

We call the DHCP step-by-step process DORA. It's a four step process that includes, Discover, Offer, Request, and Acknowledge. Let's talk more about it:

1. Discover. When you connect your device to a network, it broadcasts a discovery message to all devices on the network. The broadcast nature of this message ensures that it reaches potential DHCP servers. It's like it's saying I need an IP address and the necessary configurations to be able to connect to the network.

2. Offer. Upon receiving the Discover message, DHCP servers on the network evaluate the request. If a server determines that it can fulfill the client's request for an IP address and other configuration parameters, it responds with a DHCP Offer. This Offer includes an available IP address, lease duration, subnet mask, default gateway, DNS server, and any other relevant configuration details.

3. Request (R): After receiving one or more DHCP Offers, the client decides which offer to accept. It then sends a DHCP Request message to the chosen DHCP server, indicating its acceptance of the offered configuration.

4. Acknowledge (A): The DHCP server that receives the Request message acknowledges the client's acceptance by sending a DHCP Acknowledge (ACK) message. This message finalizes the lease agreement, and the client can now use the provided IP address and configurations

Hello Torogi, can you explain how to prevent Rogue Routers, the one that disrupts the whole network system when you plug a random router into the system and disrupts all the computer's IP address, because of the new router's DHCP. Thank you.
