dhcpd with mask 255.255.255.255 for client

Hello

Situation: I'm running isc-dhcpd on an eth0.

Prob: dhcpd.conf

Requirement:
The clients shall receive an IP from the server within a range of
10.0.0.2 to 10.0.0.200.
AND a subnet-mask of 255.255.255.255
AND a broadcast-ip of their OWN ip, e.g. 10.0.0.43 or 10.0.0.44
respectively.

For the client ifconfig output should look like this:
eth0: ip 10.0.0.66 mask:255.255.255.255 broadcast 10.0.0.66

ANY HELP IS HIGHLY APPRECIATED!!

Thanks..

Why in the world would you want that? That means that it is able to talk
only to itself, in which case why have dhcp at all.

Maybe if you told us what you want to accomplish with this, someone
might help, instead of telling us the solution you want to achieve.

Oh... anybody here able to help with this? it's URGENT!

Because they shall only be allowed to talk to themselves!! All other
packets will be routed to the gateway. Simple enough, hm?

That's not the "solution", that's the task. Dont mix it up.

Any HELP is highly appreciated! THANKS!

It is a bizarre setup. You can't blame people for wondering how it's
supposed to work.

Have you tried overriding the netmask with the subnet-mask option, something
like:

subnet 10.0.0.0 netmask 255.255.255.0
{
option subnet-mask 255.255.255.255;
range 10.0.0.2 10.0.0.200;
}

You don't need to specify the broadcast address.
