Dynamic Host Configuration Protocol (DHCP) is an IP standard for the use of DHCP servers as a way to manage dynamic allocation of IP addresses and other related configuration details for DHCP-enabled clients on your network.

The server database includes the following:

Valid configuration parameters for all clients on the network.

Valid IP addresses maintained in a pool for assignment to clients, plus reserved addresses for manual assignment.

Duration of a lease offered by the server. The lease defines the length of time for which the assigned IP address can be used.

With a DHCP server installed and configured on your network, DHCP-enabled clients can obtain their IP address and related configuration parameters dynamically each time they start and join your network. DHCP servers provide this configuration in the form of an address-lease offer to requesting clients.

On each DHCP server full consecutive range of possible IP addresses for a network is maintained called Scope. Pooled addresses are eligible for dynamic assignment by the server to DHCP clients on your network. Scopes also provide the primary way for the server to manage distribution and assignment of IP addresses and any related configuration parameters to clients on the network. The client computer can use an assigned IP address for a period of time called lease specified in DHCP server.Before the lease expires, the client typically needs to renew its address lease assignment with the server. A lease becomes inactive when it expires or is deleted at the server. The duration for a lease determines when it will expire and how often the client needs to renew it with the server. You use a reservation to create a permanent address lease assignment by the DHCP server. Reservations assure that a specified hardware device on the subnet can always use the same IP address.
