Folks,

This is Shin Miyakawa from NTT Communications in Tokyo.

First of all, thank you very much for many warm messages 
from around the world for us. 
However still the situation has not been stabilized yet here in Japan,
we're just fine and I believe that it would be improved soon.

Then, I'd like to make a comment as one of authors of the CGN requirement draft...

Talking about our CGN requirements draft,
we think that CGN is not security device whereas it seems to me that
some people believe CGN should has SECURITY function.
Rather than that, CGN should implement FAIRNESS among the users behind.

This is the original intention of the draft.

Please note well also that because IPv4 address is going to be running out,
to keep end-to-end principle as the Internet should have,
we should move to IPv6 as quick as possible.
CGN ans other similar techniques are just a quick relief, 
not a fundmental solution.
So please do not expect "perfect" to the CGN and friends.

Best regards,

Shin Miyakawa
