LXD container IP address changes

Hi LXD folks, I need your support to solve following issue.
After VM host holding lxd containers was restarted my juju controller lxd container got different IP (172.30.30.174) comparing to initial one 172.30.30.175. The later IP was assigned to completely different container without juju service. So I could not reach controller due to IP mismatch. I manually exchanged IPs between those two containers but after some time previous IP got assigned back ( juju-212b45-0 and pro-on-prem):

Is there any efficient way to assign proper IP to the container on lxd managed network without risk to be reassigned to another?

lxd is no longer supported on linuxcontainers.org, since Canonical took lxd in-house.

You can get community support for lxd on the Canonical discourse server: https://discourse.ubuntu.com/c/lxd/126
