Abstract
Mobile IPv6 (MIPv6) defines a new Mobility header that is used by
mobile nodes, correspondent nodes, and home agents in all messaging
related to the creation and management of bindings. Mobile IPv6
nodes need the capability to identify themselves using an identity
other than the default home IP address. Some examples of identifiers
include Network Access Identifier (NAI), Fully Qualified Domain Name
(FQDN), International Mobile Station Identifier (IMSI), and Mobile
Subscriber Number (MSISDN). This document defines a new mobility
option that can be used by Mobile IPv6 entities to identify
themselves in messages containing a mobility header.

1. Introduction
The base specification of Mobile IPv6 [RFC3775] identifies mobility
entities using an IPv6 address. It is essential to have a mechanism
wherein mobility entities can be identified using other identifiers
(for example, a Network Access Identifier (NAI) [RFC4282],
International Mobile Station Identifier (IMSI), or an application/
deployment specific opaque identifier).
The capability to identify a mobility entity via identifiers other
than the IPv6 address can be leveraged for performing various
functions, for example,
o authentication and authorization using an existing AAA
(Authentication, Authorization, and Accounting) infrastructure or
via an HLR/AuC (Home Location Register/Authentication Center)
o dynamic allocation of a mobility anchor point
o dynamic allocation of a home address
This document defines an option with a subtype number that denotes a
specific type of identifier. One instance of subtype, the NAI, is
defined in Section 3.1. It is anticipated that other identifiers
will be defined for use in the mobility header in the future.
This option SHOULD be used when Internet Key Exchange (IKE)/IPsec is
not used for protecting binding updates or binding acknowledgements
as specified in [RFC3775]. It is typically used with the
authentication option [RFC4285]. But this option may be used
independently. For example, the identifier can provide accounting
and billing services.

2. Terminology
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. Mobile Node Identifier Option
The Mobile Node Identifier option is a new optional data field that
is carried in the Mobile IPv6-defined messages that includes the
Mobility header. Various forms of identifiers can be used to
