Hi all, Sory I'm new to this and I'm trying to analyse the DHCP packets between clients and the servers. I don't have that much information on the whole network. Will using bootp filter helps me to put together the whole flow ?

I can see thet 192.168.70.x are coming form clients and 192.168.100.1 seems to be the DHCP server ?

That's it.

You can just use the display filter: bootp

You can see the DHCP messages:

DHCP Discover - Client to server

DHCP Inform - Client to server

DHCP ACK - Server to Client

Further infos you can find here: https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

You can also add the ethernet address(eth.addr) of the client and using "bootp". This will be a better filter as your nic might also capture Dhcp messages of other devices in the network.
