Technical Summary
The goal of Link-Local Multicast Name Resolution (LLMNR) is to enable
name resolution in scenarios in which conventional DNS name
resolution is not possible. LLMNR supports all current and future
DNS formats, types and classes, while operating on a separate port
from DNS, and with a distinct resolver cache. Since LLMNR only
operates on the local link, it cannot be considered a substitute for
DNS.
Working Group Summary
This document is a work item of the DNSEXT WG.
In the early stages, there was a great deal of contention regarding
which of two roughly equivalent mechanisms the WG would use as
the basis of this work. Some disagreement persists about whether
the WG made the best choice, given non-technical factors, such as
market position.
The WG now is asking that this document be published as Informational.

Protocol Quality
This document has been reviewed for the IESG by Margaret Wasserman
and Mark Townsley.
Note to RFC Editor
OLD:
[b] IPsec ESP with a null-transform MAY be used to authenticate unicast
LLMNR queries and responses or LLMNR responses to multicast
NEW:
[b] IPsec ESP with a NULL encryption algorithm MAY be used to
authenticate
unicast LLMNR queries and responses or LLMNR responses to multicast
IESG Note
This document was originally intended for advancement as a Proposed
Standard, but the IETF did not achieve consensus on the approach. The
document has had significant review and input. At time of publication,
early versions were implemented and deployed.
