I hope you can spare some time to help me as you did before on DHCP. I found the screenshot attached about the DORA packet and it all got me confused. As I prepare for CCNA I read Wendell's book and was under the impression that the DHCP relay router was changing the addresses to SIP=1.1.1.254, m2 and DIP100.1.1.1, m5 up to the DHCP (discover ...

IF a DHCP daemon replies directly to a client's MAC address and IP address, how does the client know that the reply is indeed for it - for at this stage, the client doesn't know its IP address. However, if the reply comes to the 255.255.255.255 broadcast address, then the client can legitimately assume that the packet os one it should process.

1) If there were many hosts in the LAN- then it would be same process ,Client would broadcast to discover DHCP server ,switch will receive it and will add the source mac-address of the client to its mac-address table and will forward it to every device knowing that it is a broadcast (FFFF.FFFF.FFFF) router receives it and would examine the ...

DHCP Lease (DORA) Process:-A DHCP lease is a temporary assignment of an IP address to a device on the network. When using DHCP to manage a pool of IP addresses, each client served on the network is only “renting” its IP address. Thus, IP addresses managed by a DHCP server are only assigned for a limited period of time.

Then this is the DHCP Offer - Transaction ID 0x39f packet. In this packet you can see the IP Address the DHCP Server will allocate to the client which is 10.0.0.2 . Next is the DHCP Request - Transaction ID 0x39f. The DHCP Request Packet contains the Requested IP Address which was offered by the server . Last is the DHCP ACK - Transaction ID ...

This is a fun process. DHCP works using the DORA-process, or what is commonly called these four steps:-Discover.-Offer-Request-Acknowledge . The logic is like this.... Discover phase. The client doesn't know anything about the network, it's trying to …
