Yes, I understand that.  The issue is that the word "tap" has
different connotation than does "splitter".  IME "tapping" implies
cutting/probing whereas "splitting" (may imply that but usually)
implies a plug-and-play solution.

YMMV,

Hi guys

I want to know that can I make my computer the DHCP server which can
dynamically allocate the IP address to my embedded development board and
made my PC and board to communicate over the crossover cable.


regards

You should start with simpler things:

  - assign a fixed address to the device and ping it, then
  - make a BOOTP server and make the device use it

DHCP is an extension of BOOTP.

For details, you could start at
<https://en.wikipedia.org/wiki/Bootstrap_Protocol>.

There is a problem in using a PC as a server: most operating
systems obey the recommendation of not allow normal user code
to serve ports below 1024.

If you're using Linux, maybe the simplest BOOTP/DHCP server
is dnsmasq.

There's no "maybe" about it - dnsmasq is very clear and simple, and
should definitely be the first choice for a DHCP server.  Don't bother
with BOOTP - go straight to DHCP.

"Dual DHCP DNS Server" is good.
