Networking :: DHCP Script - Assigning Multiple IP Addresses By Mac?

Ive been trying to give certain clients an IP adres by mac adress. For this I use the folowing code:

host apex {
hardware ethernet 00:00:00:00:00:00;
fixed-address 192.168.250.100;
}

This works perfectly, however when I try to add a second client this way it doesnt. I tried to add the above code multiple times as a whole (2 times the above code) but that doesnt work. I also tried to just add more lines under host apex but this also doesnt work.

So my question is: How do I add more of this mac related IP adress assignments in the dhcp.conf?
