2016 DHCP server - best scope/exclusions/reservations practices RRS feed

  • Question

  • For a particular subnet, is the "preferred" setup to set the scope to cover the entire subnet then set the exclusion range inside the scope and put reservations there?  Or set the scope to the IP range I want to dynamically assign and have my reservations in the non-scoped range?  Both will work, correct?

    If I have a scope that covers the whole subnet with dynamic addresses already assigned, what is the best way to add an exclusion range?  Do I figure out what's not assigned and use those IPs for my exclusions?  What if I want a particular range and there are already leases in that range?

    And am I right in thinking that the DHCP server will let me create a reservation inside the dynamic IP pool (not convert a dynamic IP to reserved but create a new reservation)?  This seems like a bad practice.

    Thanks in advance.

  • Hi,

    • Both methods are feasible.
    • The exclusion range can only be done when creating a new scope.
    • You can end the lease by running ipconfig/release on the client.
    • If you do not exclude the reserved address from the scope, it may cause an address conflict.
