SNAT with multiple mappings: subinterfaces needed?

The Netfilter NAT HOWTO shows this as an example to source NAT to multiple
source IPs:

iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 1.2.3.4-1.2.3.6

I've successfully gotten this to work as expected if I use a single "--to"
address, and the Internet interface -uses- that address, but it fails every
time I try to use a multiple SNAT list, and I feel that it is because my
machine is not answering ARP requests for those other IPs. Do I need to add
a subinterface for each IP I want to SNAT to? Or is there a much simpler
command I haven't learned yet?

Thanks in advance.

Solved my own problem ... I just had to add the IP for each in the list,
such as:

ip addr add 1.2.3.4/24 dev eth0
