the dns is 8-bit clean. bangs, dots (not as separators), blanks, etc.

Hi there,
as 2-byte ASNs are close to depletion (see NRO announcement this week),
we have come across a topic, that might influence the adoption of 4-byte

adoption and are therefore unable to evaluate, if we should rush for the

Re-reading, I was thinking of someone connecting to an IXP, not a new IXP
needing a 2Byte.This is an interesting situation and you are correct,
my comment was off topic.

Specifically, fails miserably if you use RSVP-TE to build
your MPLS backbone.

Again, only an issue when using RSVP-TE.

A path to a destination must be loop free, irrespectively.
So it is not a combination of multiple but rather a list of loop free paths to
a destination where any other metrics are used as tie-breakers.

Yes, a /27 is too small. You need at least a /24.

Sure, but the text I quoted is about ARIN allocation
I would imagine this should be announced with the larger block owner.

Perhaps instead of trying to do this as a new independent activity (with
all of the difficulties that entails), the community would be better served
by documenting this information as a BCOP or two or three???
