You can use OS X Server to offer DHCP service on multiple network interfaces. This capability provides a simple way to set up and administer computers. The user can then access network services without any manual intervention. If a network has been engineered properly, a new user can take a new Mac out of the box, connect to either a wired or wireless network, and automatically configure the computer with appropriate networking information. When the DHCP server provides this configuration information, you are guaranteed that users will not enter incorrect information when configuring their network settings.

This negates the need to manually configure the information on each computer or device. At this time, the host has a valid IPv4 address and can start using the network.Ī key benefit provided by the DHCP server in this example is the assignment of configuration information to each host on the network.

The DHCP server formally acknowledges that the host can use the settings it requested.

The host replies to the first DHCP offer it sees on the network it sends a request for the IPv4 address of 172.16.16.5, the setting that the DHCP server just offered it.

In this example, the DHCP server proposes that the host use an IPv4 address of 172.16.16.5, along with some other network settings, including a valid subnet mask, router, DNS servers, and default search domain.

A DHCP server receives the request from the host and responds with the appropriate information.

It broadcasts a request over its local network to see whether a valid DHCP service is available.

A computer or device (host) on the network is configured to obtain network configuration information via DHCP.

The process followed by a DHCP server granting an address to a client is well documented. Learn More Buy Reference 19.1 Describing How DHCP Works Apple Pro Training Series: OS X Server Essentials 10.10: Using and Supporting OS X Server on Yosemite
