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

Reported by: Richard Hartmann <[email-masked]>
Date Reported: 2014-02-06
Rejected by: Brian Haberman (IESG)

Section: 4.2.2.

Original Text
-------------
4.2.2.  Handling One 16-Bit 0 Field

   The symbol "::" MUST NOT be used to shorten just one 16-bit 0 field.
   For example, the representation 2001:db8:0:1:1:1:1:1 is correct, but
   2001:db8::1:1:1:1:1 is not correct.

Corrected Text
--------------
4.2.2.  Incorrect use of "::"

   The symbol "::" MUST NOT be used to shorten just one 16-bit 0 field.
   For example, the representation 2001:db8:0:1:1:1:1:1 is correct, but
   2001:db8::1:1:1:1:1 is not correct.

   The symbol "::" MUST NOT be used just so. For example, the
   representation 2001:db8:1:1:1:1:1:1 is correct, but
   2001:db8:1:1::1:1:1:1 is not correct.

Notes
-----
You would think this should be obvious, but I have seen actual discussions that 2001:db8:1:1::1:1:1:1 is correct syntax. Explicitly forbidding this form does no harm and stops all discussions in this direction.

Thanks for your work.
 --VERIFIER NOTES-- 
As agreed to by the document authors and the submitter, there is a reference to RFC 4291 that addresses the concern.
