The following errata report has been submitted for RFC5952,
"A Recommendation for IPv6 Address Text Representation".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=5952&eid=2872

--------------------------------------
Type: Technical
Reported by: Richard J. Smith <rjsmith2@cisco.com>

Section: 5

Original Text
-------------
For these addresses, mixed notation is RECOMMENDED if the following condition is met: the address can be distinguished as having IPv4 addresses embedded in the lower 32 bits solely from the address field through the use of a well-known prefix.


Corrected Text
--------------
For these addresses, mixed notation is RECOMMENDED if the following conditions are met: the address can be distinguished as having IPv4 addresses embedded in the lower 32 bits solely from the address field through the use of a well-known prefix, and the entire address is not either the unspecified IPv6 address "::" or the loopback IPv6 address "::1".


Notes
-----
RFC-4291 defines the 80-bit all-zeros prefix as indicating an "IPv4-compatible IPv6 address". Without further clarification in section 5 of RFC-5952, the recommended formatting of the IPv6 unspecified address would be "::0.0.0.0", and the recommended formatting of the IPv6 loopback address would be "::0.0.0.1". Neither of these recommended representations is desirable.

Instructions:
-------------
This errata is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
can log in to change the status and edit the report, if necessary.
