Abstract

   This option is used by a Dynamic Host Configuration Protocol (DHCP)
   client to optionally identify the type or category of user or
   applications it represents.  The information contained in this option
   is an opaque field that represents the user class of which the client
   is a member.  Based on this class, a DHCP server selects the
   appropriate address pool to assign an address to the client and the
   appropriate configuration parameters.  This option should be
   configurable by a user.

1. Introduction

   DHCP administrators may define specific user class identifiers to
   convey information about a client's software configuration or about
   its user's preferences.  For example, the User Class option can be
   used to configure all clients of people in the accounting department
   with a different printer than clients of people in the marketing
   department.
