Containers on a different sub net with same bridge?

Hello im wondering if so is possible i have my lxd bridge interface giving ips on 10.0.0.0/8 network then i could proceed in giving them a static ip but im wondering if i can put them in a different subnet without making a new bridge. ex.10.10.0.0/16

Yes.

lxc init ubuntu:16.04 c1
lxc network attach lxdbr0 c1 eth0
lxc config device set c1 eth0 ipv4.address 10.0.3.123
lxc start c1

This way your container receives a static ip

yes i know that but what i am looking to do is set a specific sub net so instead of it being on the same sub net as the bridge so 10.0.0.0/8 it goes on a 10.10.0.0/16 sub-netted network.
