On 21 May, we issued a closing response to ACSP 2019.10: CIDR Notation
in ARIN-issued emails. Please see the full text of our response and the
suggestion below or online at:



Thank you for your suggestion, numbered 2019.10 upon confirmed receipt,
suggesting that we use CIDR notation in the arin-issued report to make
it easier to scan for block sizes.

The format of the arin-issued report was defined through a Community
(see:https://www.arin.net/vault/announcements/2009/20090102.html). We
have reason to believe that community members process this report
through scripting, and that to make a change to the format of the report
would create problems for those users. Out of an abundance of caution,
we will not be making a change to the format of the report at this time.

Thank you for your participation in the ARIN Consultation and Suggestion
Process.  This suggestion is now closed.


Description: CIDR notation on ARIN-issued emails

Value to Community:

Easier to read than the current XXX.XXX.XXX.XXX-YYY.YYY.YYY.YYY

e.g. change “Add” to “Add”

I like to scan the list for the sizes of the blocks.
