Subject: [BEHAVE] [Errata Rejected] RFC7050 (6270)

From: RFC Errata System <[email-masked]>
Date: Wed, 13 Jan 2021 07:12:22 -0800 (PST)

The following errata report has been rejected for RFC7050,
"Discovery of the IPv6 Prefix Used for IPv6 Address Synthesis".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6270

--------------------------------------
Status: Rejected
Type: Technical

Reported by: Mark Andrews <[email-masked]>
Date Reported: 2020-09-01
Rejected by: Magnus Westerlund (IESG)

Section: 3.4

Original Text
-------------
"PTR" query #2 for "2001:db8:43::192.0.0.170

Corrected Text
--------------
"PTR" query #2 for "2001:db8:43::192.0.0.171

Notes
-----
The second PTR query should be for the reverse of the DNS64 mapped well known address 192.0.0.171.  This looks like a cut-and-paste error where 170 was not changed to 171.
 --VERIFIER NOTES-- 
After discussion on Behave mailing list it appears that the example is not in contradiction with what the RFC specifies. There was some additional discussion around this for other potential improvements that should be considered in case the specification is revised.
