scope:

This document defines a new Dynamic Host Configuration Protocol (DHCP) option through which authorization tickets can be easily generated and newly attached hosts with proper authorization can be automatically configured from an authenticated DHCP server. DHCP provides a framework for passing configuration information to hosts on a TCP/IP network. In some situations, network administrators may wish to constrain the allocation of addresses to authorized hosts. Additionally, some network administrators may wish to provide for authentication of the source and contents of DHCP messages.
