A code identifies each DHCP option. It can be expressed in value 0 to 255 by user con-
figuration and some of them are predefined in the standards. (128 ~ 254 is site specific) A
length can be variable according to value or can be fixed. A value contains actual infor-
mation such an IPv6 address, string, or index, which is inserted into the DHCP packet.
Administrators can configure a DHCPv6 option format in
