As far as I got it, LISP-DDT is based on the ideas of LISP-TREE, which
is based on DNS. Just in case you're not familiar with LISP-TREE, take a
look on this paper for more information:

Nifty idea, as a dns operator that would make it easy for us :)
Having said that, dns is useful as a common point of reference to help explain
ddt but has significant enough differences (and the joy of dodging legacy
baggage) to make a separate protocol a sensible option.

Subject: [lisp] DDT vs DNS
Hi,
During wg meeting today all presentations LISP-DDT, LISP-DDT-SEC and
LISP-DDT Database Transfer stated that this is very much like DNS.
Likewise the drafts say it too:
http://tools.ietf.org/html/draft-fuller-lisp-ddt-00
Conceptually,
this is similar to the way that a client of the Domain Name System
(DNS) follows referrals (DNS responses that contain only NS records)
from a series of DNS servers until it finds an answer.
http://tools.ietf.org/id/draft-wiley-lisp-ddtxfer-01.txt
Think of a LISP-DDT query as the analog to a DNS name server (NS)
query, and a LISP map request as the analog to a DNS address (A)
query (LISP-DDT does not store the EID to RLOC mappings returned in a
map request).
Said this I would like to ask why not use new instance of DNS with
DNSSEC completely independent on current name resolution DNS here ?
It walks like a duck .. it quacks like a duck .. it must be a duck !
Defining new set of records and leveraging a lot of work which went into
(and still going) into DNS one could think would make a lot of sense
rather then reinventing the wheel.
If not .. if DDT approach can not be serviced by DNS architecture I
think it would be very useful to document why. Also in the same time it
would be great to announce plans for open source DDT support ?
Many thx,
R.
