                         draft-ietf-pcp-dhcp-05

Abstract

   This document specifies DHCP (IPv4 and IPv6) options to configure
   hosts with Port Control Protocol (PCP) Server names.  The use of
   DHCPv4 or DHCPv6 depends on the PCP deployment scenario.

Internet-Draft              PCP DHCP Options              September 2012

1.  Introduction

   This document defines DHCPv4 [RFC2131] and DHCPv6 [RFC3315] options
   which can be used to provision PCP Server [I-D.ietf-pcp-base] names.
   Motivations for defining PCP option as a name and not an IP address
   are discussed in Appendix A.

   In order to make use of these options, this document assumes
   appropriate name resolution means (e.g., Section 6.1.1 of [RFC1123])
   are available on the host client.

   The use of DHCPv4 or DHCPv6 depends on the PCP deployment scenarios.
