Configuring DHCP SERVER

2. What do you mean by DHCP scope? List the corresponding features (with a brief description for each feature) associated with the new scope wizard?

DHCP scope

• A DHCP scope is a pool of IP addresses within a logical subnet, such as 192.168.0.11 through 192.168.0.254, that the DHCP server can assign to clients.
• Scopes provide theessential means for the server to manage distribution and assignment of IP addresses and of any related configuration parameters to clients on the network.

DHCP lease

• An IP address within a defined scope that is offered to a DHCP client is known as a lease. When a lease is made to a client, the lease is active.
• Each lease has a specified duration, and the client must periodically renew the lease if the client is going to continue to use the address. The default lease duration value is eight days.

■ Add Exclusions page This page allows you to specify the IP addresses within the defined range that you do not want to lease to DHCP clients.

■ Lease Duration page This page allows you to define the lease duration values.These lease durations are then assigned to DHCP clients.

■ Configure DHCP Options page This page allows you to determine whether to configure DHCP options for the scope through subsequent pages

■ Router (Default Gateway) page (optional) This page allows you to specify which default gateway (and alternates) should be assigned to DHCP clients.

■ Domain Name And DNS Servers page (optional) This page allows you to specify both the parent domain to be assigned to client computers and the addresses of DNS servers
