Hi Tom,
The existing text does not make it clear whether "::" MUST
always be used if there are at least two consecutive 16-bit 0 fields.
This leads to ambiguity in address representations. Hence, I support the
modified text that Kawamura-san proposed.
Cheers
Suresh

I think that the existing text is clearer than the text you want to replace it
with.

Hi
This already came up on the list once before,
and since its in AUTH48 now, I would like to
make the changes to the document.
Current section 4.2 has 3 parts, and the first two are
4.2.1. Shorten as Much as Possible
The use of the symbol "::" MUST be used to its maximum capability.
For example, 2001:db8::0:1 is not acceptable, because the symbol "::"
could have been used to produce a shorter representation 2001:db8::1.
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.
I would like to combine these two, and also clarify that you MUST
use "::" when there are more then two consecutive 0 fields.
The following is the text I plan to use.
4.2.1. When to use "::"
If the address contains at least two consecutive 16-bit 0 fields, "::"
MUST be used to compress all consecutive 16-bit 0 fields.
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.
Please let me know by Aug 6, 2010 if you have any objections to this.
Thanks and Regards,
Seiichi
