[U-Boot-Users] bootp/dhcp

	but the idea is to get a dynamic ip address, why do we need to
change the DHCP server settings to give a special DHCP response to our
machine.  I have seen this happening with the linux kernel.  The kernel also
requests for a ip address using DHCP and then uses that ip address.
Since an ideal way for a bootup is that I connect my device to the network,
get and dynamic ip address and download the kernel from a remote machine.

This might be paranoid but is it possible with u-boot currently...???

That advice is for the paranoid.  You can put your embedded dev board
on a network with other machines, including a DHCP server, as long as
the address you get from the server will satisfy your needs.  There
are ways of coercing the DHCP server to deliver a special DHCP
response for your machine.  In the case of the 'corporate' network,
you may not have the option to twiddle the DHCP configuration.
