Hi, Do you know how to release private ip address? Thx

example: instace1 allocate ip:10.10.0.1 I will terminate this instance, but ip address is still allocated for this instance. I want to release this address back to pool.

Restart VM . It will cause new DHCPREQUEST, new DHCPACK from dnsmasq

Even if terminate instance the new instance will take new ip address... so after while pool is exhausted

Disable DHCP option for private network. Assign IP from proper subnet manually.

Private network has two options : 1.DHCP enabled , 2. DHCP disabled. It's the way Neutron L2 Layer works (neutron-openvswitch-agent works) for ML2&OVS&GRE(VLAN) and OVS&GRE(VLAN) Setups.
