How to improve DHCP management inside company

Hi all,
Inside company there is CLIENT Vlan (VLAN 192.168.10.0/24) and SERVER Vlan (192.168.15.0/24).
Inside Server VLAN there are two domain controllers.
They manage DHCP inside company too.

Between Client and Server networks there is hardware firewall.
All company clients (Inside Client VLAN) are joined to Windows Domain.

Is it possible create multiple DHCP scope for the same VLAN?
I would create mutiple DHCP scope for the same VLAN based on Computer Security Group.

For example I have two groups of laptops:
Group A --> DHCP Scope A (192.168.10.50-->192.168.10.55)
Group B --> DHCP Scope B (192.168.10.70-->192.168.10.150)

Can IPAM help me to configure my request?

All clients are Windows 10 Pro and Server has got Win 2016 DataCenter.

Best regards

Hi ，

Is it possible create multiple DHCP scope for the same VLAN?

You cannot have multiple scopes for the same /24 network on the same DHCP server. You need to
split the scope between 2 DHCP servers and set MAC reservations to ensure that the correct DHCP server provides the IP.

The similar thread discussed before, you could have a look:
