  • Hi Superhl,

    >>Do I need or can I break this up...

    It based on your requirement, could you please provide details of your network topology to here for further support.

    Or You could create one scope 10.100.1.1-10.100.2.254, and configure network mask be 255.255.255.254.0.

    Best Regards

    John

  • My current setup 10.100.0.1/21 subnet mask 255.255.248.0

    In DHCP properties, the current setup is Start 10.100.0.1 End 10.100.2.254. I know I can expand this to 10.100.7.254 but I don't need that many addresses. I was just wondering would it be best practice to create a scope for the following:

    scope 1 start 10.100.0.2 end 10.100.0.254

    scope 2 start 10.100.1.2 end10.100.1.254

    and so forth. Which is best practice.

    With current setup, a device will get a 10.100.2.0  ip address and a 10.100.1.255
