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 not expressing the PCP option as a 32 or 128-bit
binary 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.
2. Terminology
