Each node group has assigned a particular set of networks. Each node can be assigned to one particular node group. Assume the following situation where you have Node 1 in node group A and Node 2 in node group B.

Node group A has following subnets
Admin - net A1 - 10.0.1.0/24
Mgmt - net B1- 10.0.2.0/24
Private - net C1- 10.0.3.0/24
Public - net D1- 10.0.4.0/24
Storage - net E1- 10.0.5.0/24

Node group B has following subnets
Admin - net A2 - 172.16.1.0/24
Mgmt - net B2 - 172.16.2.0/24
Private - net C2 - 172.16.3.0/24
Public - net D2 - 172.16.4.0/24
Storage - net E2 - 172.16.5.0/24

What do you have to do to achieve below scenario
Node 1
Admin - net A1 - 10.0.1.10
Mgmt - net B1- 10.0.2.10
Private - net C1- 10.0.3.10
Public - net D1- 10.0.4.10
Storage - net E1- 10.0.5.10

Node 2
Admin - net A2 - 172.16.1.10
Mgmt - net B2 - 172.16.2.10
Private - net C2 - 172.16.3.10
Public - net D2 - 172.16.4.10
Storage - net E1 - 10.0.5.11

How will Fuel manage IP addresses for Storage network E1?

Can we use the same subnets for different node groups and have a certainty that IP addresses from this subnet will be properly managed across different node groups?
