Great, thanks to your very quick answer.

I thought it would be to make a group out of it to make it easier to manage:

group {
         option routers 192.168.x.1;
         host HOST1 { hardware ethernet 00:50:56:94:3C:6F; fixed-address 
192.168.x.152; }
         host HOST2 { hardware ethernet 00:0f:fe:8a:5a:cf; fixed-address 
192.168.x.151; }

My tests tell me that it works, does it make sense?
