      Resource Records for EUI-48 and EUI-64 Addresses in the DNS
               draft-jabley-dnsext-eui48-eui64-rrtypes-05

Abstract

   48-bit Extended Unique Identifiers (EUI-48) and 64-bit Extended
   Unique Identifiers (EUI-64) are address formats specified by the IEEE
   for use in various layer-2 networks, e.g.  Ethernet.

   This document describes two new DNS resource record types, EUI48 and
   EUI64, for encoding Ethernet addresses in the DNS.

   This document describes potentially severe privacy implications
   resulting from indiscriminate publication of link-layer addresses in
   the DNS.  This document recommends that EUI-48 or EUI-64 addresses
   SHOULD NOT be published in the public DNS.  This document specifies
   an interoperable encoding of these address types for use in private
   DNS namespaces, where the privacy concerns can be constrained and
   mitigated.

Internet-Draft     Resource Records for EUI-48, EUI-64         June 2013

1.  Introduction

   The Domain Name System (DNS) is described in [RFC1034] and [RFC1035].
   This base specification defines many Resource Record Types (RRTypes),
   and subsequent specifications have defined others.  Each defined
   RRType provides a means of encoding particular data in the DNS.
