Public bug reported:

Description
===========
When trying to create attach a fixed ip (be it a provider IP) to an instance directly, I see different behaviour when using `nova interface-attach` and `openstack server add fixed ip`. The former assigns the ip successfully whereas the latter assigns a different ip in the same network

Steps to reproduce
==================
1. Create VM
2. Attach interface with `nova --debug interface-attach --net-id <netid> --fixed-ip <ip> <serverid>`
3. Remove interface with `openstack server remove network <serverid> <netid>`
4. Attach interface with  openstack --debug server add fixed ip <serverid> --fixed-ip-address <ip> <netid>`

Expected result
===============
Both 2) and 4) should lead to the requested IP be attached

Actual result
=============
Only 2) assigns requested ip. 4) assigns a different ip in the same network.

Environment
===========
1. Exact version of OpenStack you are running? Yoga (nova 25.0.1)

2. Which hypervisor did you use? Libvirt 8.0.0 + KVM 4.2.1
   What's the version of that? 

2. Which storage type did you use? Ceph

3. Which networking type did you use? Neutron with OVN

Logs & Configs
