A multi-interfaced node is connected to multiple networks, some of
which might be utilizing private DNS namespaces.  A node commonly
receives recursive DNS server configuration information from all
connected networks.  Some of the recursive DNS servers might have
information about namespaces other servers do not have.  When a
multi-interfaced node needs to utilize DNS, the node has to choose
which of the recursive DNS servers to use.  This document describes
DHCPv4 and DHCPv6 options that can be used to configure nodes with
information required to perform informed recursive DNS server
selection decisions.  [STANDARDS-TRACK]
