IMPOSSIBLE : cisco switch : how to give a device this IP

SO i am trying to configure a client (STB) to get the following IP : 225.50.50.52; (yes its a multicast )
and the host can take any IP ;
the host and client must be on the same VLAN.
the host will stream the image to the client.

i am using a 3560 cisco switch , but the problem is this IP is reserved , see the output:

—————————————————————————-
Switch(dhcp-config)#address 225.50.50.52 hardware-address 0002021FF9FC
% This command may only be used with ‘network’ pools
—————————————————————————–
any idea how to bypass this or how can i give the device this multicast IP

thx ur my savior
