In dhcpd.conf it is legal to have more than one address in the
fixed-address statement.

For example if you have one host which might need fixed addresses in
more than one subnet you can use:

host mylaptop {
  hardware ethernet c:0:f:f:e:e;
  fixed address 192.168.1.1, 192.168.2.20, 192.168.50.99;
}

Can you do this with omapi commands? Select using the mac address, then
add multiuple IP addresses?

set ip-address = 192.168.1.1, 192.168.2.20, 192.168.50.99

I'm not able to test this here, but it might be worth trying.
