--------------------------------------
Status: Verified
Type: Technical

Reported by: Robert Edmonds <edmonds@mycre.ws>
Date Reported: 2016-07-08
Verified by: Joel Jaeggli (IESG)

Section: 13

Original Text
-------------
   7.   Due its internal implementation, ANS finds a response that is
        tailored for the whole /16 of the client that performed the
        query.

   8.   ANS adds an ECS option in the response, containing:
[...]
        *  SCOPE PREFIX-LENGTH set to 0x30, indicating a /48 network.

Corrected Text
--------------
   7.   Due its internal implementation, ANS finds a response that is
        tailored for the whole /48 of the client that performed the
        query.

   8.   ANS adds an ECS option in the response, containing:
[...]
        *  SCOPE PREFIX-LENGTH set to 0x30, indicating a /48 network.

Notes
-----
The prose description in step 7 does not match the ECS option described in step 8. Either both should say "/16" or both should say "/48". Probably /48 was meant, since a /16 would be a huge amount of IPv6 address space.
