Even in a Discover? Maybe I am missing something but all I can find is
this:

"  If a server receives a DHCPREQUEST message with an invalid 'requested
   IP address', the server SHOULD respond to the client with a DHCPNAK
   message and may choose to report the problem to the system
   administrator.  The server may include an error message in the
   'message' option."

I don't see any information on how to handle this is in a discover if I
don't want to give the client its requested IP...

DHCPNAK.  Search RFC2131 for 'Requested IP Address' option for the
answer. HTH.

I have written a DHCP server, however I can't find anything in the RFC
about how to handle Option 50, client requested IPAddress on a
DHCPDiscovery when I want to give the client a different address.  

Right now I just respond with a DHCPOffer with a different IP.  After 2
or 3 Discovers/Offers the client finally sends a request.  Am I handling
this
properly?   I would like to get rid of those 2 or 3 middle
Discover/Offers
and speed up the process a bit...


Thanks


Jeremy
