A DHCP server responds to requests from clients, dynamically assigning properties to them.

• DHCP concepts
  Dynamic Host Configuration Protocol (DHCP) provides an automated method for dynamic client configuration. Here are some DHCP-related concepts to help you better understand DHCP.

• Examples: DHCP
  By reviewing diagrams and examples of how different networks are set up, you can determine which is the best choice for your installation.

• Planning for DHCP
  Setting up Dynamic Host Configuration Protocol (DHCP) can be a time-consuming and error-prone process if you have not taken the time to plan how your DHCP server should be configured. By taking time to think about your network setup and security concerns in advance, you can configure your DHCP server more efficiently.

• Configuring DHCP
  Here are instructions for setting up your DHCP server and clients, and for configuring DHCP to send dynamic updates to Domain Name System (DNS).

• Managing leased IP addresses
  The Dynamic Host Configuration Protocol (DHCP) configuration tool can help you specify the IP address pool that DHCP manages and the lease times for those address pools. The DHCP server monitor can help you see which of the IP addresses are currently being leased.

• Troubleshooting DHCP
  Follow these guidelines when troubleshooting DHCP problems.
