Technical Summary
This document describes the reservation of Autonomous System numbers
(ASNs) that are for Private Use only and MUST NOT be advertised to
the Internet, known as Private Use ASNs. This document enlarges the
total space available for Private Use ASNs by documenting the
reservation of a second, larger range and updates RFC 1930 by
replacing Section 10.
Working Group Summary
Working group: WG list had 2 rounds of WG LC - one for approval of
draft and one for actual range size. The majority view in the
WG is that it fixes a clear operational problem in the reasonable
use of private AS numbers. The minority view is that all AS numbers
should be registered. The chairs anticipated this operational debate would
continue during IETF last call.
This issue was raised directly with the IESG and the AD
worked with the authors and chairs to remove the justification
text that appeared to be causing concern, i.e.
without loosing the generality of the expanded AS range to focus
the need to do this on the new applications such as DC which
the reviewer noted justifies the change in its own right.
Document Quality
Large DC providers (Microsoft (author)) and cloud providers
have requested to aid ral operational usage.
This is range BCP. IANA registry need to be informed.
Careful review by both WG chairs (one serving as Shepherd).
