1.  Introduction

   DHCPv6 [RFC8415] is widely used for supplying configuration and other
   relevant parameters to clients in IPv6 networks.  This document
   defines YANG [RFC7950] modules for the configuration and management
   of DHCPv6 'element' (servers, relays and clients) using the Network
   Configuration Protocol (NETCONF [RFC6241]) or RESTCONF [RFC8040]
   protocols.
