I have many devices in my environment that run on DHCP and many that simply use
BOOTP. Because of this, I need to separate the traffic in order to narrow down
packets coming from particular kinds of clients. This is not easily done
because DHCP is only processed as part of the BOOTP dissector and there are no
filtering options for DHCP (for IPv4). While DHCP was built on BOOTP it is not
BOOTP, and including DHCP in BOOTP is a critical flaw for those of us that
manage DDI.
In order to properly handle BOOTP and DHCP, Wireshark needs a DHCP filter that
includes both DHCP and BOOTP, while the BOOTP filter should ONLY INCLUDE BOOTP
PACKETS. This also allows users to separate DHCP-only traffic by filtering on
"dhcp && !bootp".
