DHCP Scope

A DHCP (Dynamic Host Configuration Protocol) scope refers to a valid series of IP addresses are offered for assignments or for lease to the client computers of a subnet. Scopes establish which of the IP addresses are granted to the clients. However, these scopes are first defined and activated prior to the use of DHCP clients.

How to Create a Scope

There are some pieces of information needed to create a new scope. You must use the DHCP console to construct a new scope. The list of requirements includes:

  • a scope tag or identity to name the particular scope;
  • a distinctive subnet mask to determine the IP address in the network;
  • a lease duration period or the length of time that a client can use the IP address; and
  • a list of all IP addresses covered within the scope.

The Lease Duration

An organization can have many IP addresses available. They usually have configurations that are seldom adjusted. The administrator can increase the duration of lease to lessen the incidence of lease renewal links between the DHCP server and the clients. These incidences are due to network traffic. DHCP-related activities can be reduced when DHCP clients have frequent renewal of their leases.

In the case of frequent client movements in and out of the network, the administrator can also make a limited number of IP addresses. The lease duration can also be reduced so the addresses can be returned to the scope for reassignment to other clients.

Other Considerations

It is quite probable to give a configuration on a DHCP client with an infinite lease period. However, this must be employed with watchful attention. Even considerably stable settings contain an undeniable number of customer turnover.

Considering the situation at the minimum level, you might consider adding or removing computer units from one area to another area. You can also make an allowance by using network adapters. In case this happens, the DHCP server must be notified of the removal of the lease so the IP address can be used to service other clients. If not, the IP address can remain unused. To avoid this occurrence, it is better to opt for reservation rather than make an infinite configuration.
