1. Introduction
The LISP architecture and protocols [RFC6830] introduces two new
numbering spaces, Endpoint Identifiers (EIDs) and Routing Locators
(RLOCs) which are intended to replace most use of IP addresses on the
Internet. To provide flexibility for current and future
applications, these values can be encoded in LISP control messages
using a general syntax that includes Address Family Identifier (AFI)
[RFC1700].
The length of the value field is implicit in the type of address that
follows. For AFI 17, a Distinguished Name can be encoded. A name
can be a variable length field so the length cannot be determined
solely from the AFI value 17. This draft defines a termination
character, an 8-bit value of 0 to be used as a string terminator so
the length can be determined.
LISP Distinguished Names are useful when encoded either in EID-
records or RLOC-records in LISP control messages. As EIDs, they can
be registered in the mapping system to find resources, services, or
simply used as a self-documenting feature that accompany other
address specific EIDs. As RLOCs, Distinguished Names, along with
RLOC specific addresses and parameters, can be used as labels to
identify equipment type, location, or any self-documenting string a
registering device desires to convey.

2. Definition of Terms
Address Family Identifier (AFI): a term used to describe an address
encoding in a packet. An address family currently defined for
IPv4 or IPv6 addresses. See [AFI] and [RFC1700] for details on
other types of information that can be AFI encoded.
3. Distinguished Name Format
An AFI=17 Distinguished Name is encoded as:
