Description: Option 15 in DHCP, known as the domain name option, is a parameter that allows DHCP servers to provide clients with information about the domain they belong to. This option is crucial for the automatic configuration of networks, as it enables connected devices to know the domain name they should use to resolve host names to IP addresses. Upon receiving this option, clients can automatically configure their name resolution, facilitating communication within the network and externally. Option 15 is defined in the DHCP (Dynamic Host Configuration Protocol) standard and is part of a broader set of options that servers can offer to clients, allowing for customization and adaptation to different network environments. This option is particularly useful in various network settings, including enterprise and educational networks, where domain name management is essential for the efficient operation of network services. In summary, option 15 not only simplifies network configuration for end users but also helps network administrators maintain more effective control over the network infrastructure.
