DHCP Client Lease Validity

  • Article

Applies To: Windows Server 2008 R2

Each time a Dynamic Host Configuration Protocol (DHCP) client starts, it requests IP addressing information from a DHCP server, including:

  • IP address
  • Subnet mask
  • Additional configuration parameters, such as a default gateway address, Domain Name System (DNS) server addresses, a DNS domain name, and Windows Internet Name Service (WINS) server addresses

When a DHCP server receives a request, it selects an available IP address from a pool of addresses defined in its database (along with other configuration parameters) and offers it to the DHCP client. If the client accepts the offer, the IP addressing information is leased to the client for a specified period of time.
