DHCP Option
DHCP provides a framework for passing information to TCP/IP network devices. Network and
other control information are carried in tagged data items that are stored in the options field of
the DHCP message. The data items themselves are also called options.
DHCP can be initiated by simply connecting the Skype for Business phone with the network.
Skype for Business phones broadcast DISCOVER messages to request the network information
carried in DHCP options, and the DHCP server responds with specific values in corresponding
options.
