DHCP servers are a popular way of configuring clients with basic networking information such as an IP address, a default gateway, network mask, DNS server, etc. Most DHCP servers have the ability to also send a variety of optional information that describes the network configuration and various services that are available on the network.
DHCP option statements always start with the option keyword, followed by an option name, followed by option data.
