+=head1 SYNOPSIS
+
+    use Net::DNS;
+    $rr = Net::DNS::RR->new('name IN EUI48 address');
+
+    $rr = Net::DNS::RR->new(
+	name	=> 'example.com',
+	type	=> 'EUI48',
+	address => '00-00-5e-00-53-2a'
+	);
+
+=head1 DESCRIPTION
+
+DNS resource records for 48-bit Extended Unique Identifier (EUI48).
+
+The EUI48 resource record is used to represent IEEE Extended Unique
+Identifiers used in various layer-2 networks, ethernet for example.
+
+EUI48 addresses SHOULD NOT be published in the public DNS.
+RFC7043 describes potentially severe privacy implications resulting
+from indiscriminate publication of link-layer addresses in the DNS.
+
+=head1 METHODS
+
+The available methods are those inherited from the base class augmented
+by the type-specific methods defined in this package.
+
+Use of undocumented package features or direct access to internal data
+structures is discouraged and could result in program termination or
+other unpredictable behaviour.
+
+
+=head2 address
+The address field is a 6-octet layer-2 address in network byte order.
+
+The presentation format is hexadecimal separated by "-".
