DHCP option space test

[Surya Teja]

Hi ,
How does a DHCP client can get the DHCP option space data from respective
server config
Ex: I have constructed my local server config as below by taking online
example references
default-lease-time 3600;
authoritative;

*option space optionSpacedb;*
*option optionSpacedb.option1d code 1 = ip-address;*
subnet 15.0.0.0 netmask 255.255.255.0 {
        pool {
           range 15.0.0.16 15.0.0.17;
        }
         option domain-name "test123.com";
       *  option optionSpacedb.option1d 5.6.7.8;*
         option routers 15.0.0.1;
         option subnet-mask 255.255.255.0;
        }
But I was stuck in testing it by DHCP clients. Do we need to do any setting
on the client side to request the option space, I have checked in other
forums but they only provide the declaration examples but no where we have
practical test examples. Can any one please help on testing it or any
reference links that can be test on real time environment. I want to know
the exact business use case for the option space module.

Thanks
