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 IP phone with the network. IP phones broadcast
DISCOVER messages to request the network information carried in DHCP options, and the
DHCP server responds with specific values in corresponding options.
The following table lists common DHCP options supported by IP phones.
Specify the client’s subnet mask.
Specify the offset of the client's subnet in seconds
from Coordinated Universal Time (UTC).
Specify a list of IP addresses for routers on the
client’s subnet.
Specify a list of time servers available to the client.
Specify a list of domain name servers available to
the client.
Specify a list of MIT-LCS UDP servers available to
the client.
Specify the name of the client.
