There is no DHCP client inside Marinetti. ADTPro uses IP65.

Here are all the DHCP routines that I know of, and my remarks on each:

- Contiki
https://github.com/oliverschmidt/contiki/blob/master/core/net/ip/dhcpc.c
This one is OK.

- PLASMA 
https://github.com/dschmenk/PLASMA/blob/master/src/libsrc/dhcp.pla
This is a pretty good one.

- IP65
https://github.com/oliverschmidt/ip65/blob/master/ip65/dhcp.s
This one is fairly good, but could be better. It does not increment the secs
field, and it does not wait until receiving an ACK from the DHCP server
before applying the offered IP configuration.

- Marina
http://marina.a2hq.com/files/src/Marina%20IP%20-%2025%20Oct%2015.2mg.gz
This one is fairly good. It follows the RFC pretty closely, but does not
implement lease renewal.


If you or anyone wants to write or improve a DHCP client, it is imperative
to read these two documents first:
http://tools.ietf.org/html/rfc2131
http://tools.ietf.org/html/rfc2132
