Hum, is this reasonable that an IPv6 WG doesn't even have IPv6
resources
?
No. They should fire the current secretariat and hire a dual-stack one.
Note I didn't say it would be sent with IPv6 all the way long from me
to
all recipients, but it was sent using IPv6 between my laptop (I of
course use an IPv6 compliant mailer) and my mail server, which is
located 50kms from where I work.
Doesn't look that way:
Received: from psg.com (mailnull@psg.com [147.28.0.62])
Received: from majordom by psg.com with local (Exim 4.44 (FreeBSD))
Received: from [203.178.142.146] (helo=mail.sfc.wide.ad.jp)
Received: from iseran.local (jules.nautilus6.org [203.178.138.2])
(What's the deal with the psg server not trusting our domain names,
anyway?)
FYI, in my office, we couldn't even get enough IPv4 addresses for
all desktop,
Strange.
Do you know how many IPv4 addresses have been allocated to each
countries in the world ?
IP addresses aren't allocated to countries. The rules are pretty much
identical for each of the regional internet registries, so for new
requests, there shouldn't be any difference where on earth the request
is made. Of course many ISPs find it useful to create an artificial
scarceness to squeeze more money out of their customers and it MIGHT be
possible that in some less developed countries the RIR fees are
problematic, but compared to other internet-related expenses these fees
aren't exorbitant.
(we could have received more IPv4 addresses if we where willing to
renumber - which we didn't want).
Aha, there the monkey comes out of the sleeve, to use a good Dutch
proverb.
Some random data points:
- of the "top 100 English language web sites" not one is reachable
over IPv6
- of the "top 100 English language web sites" one times out for AAAA
DNS requests
- of the 213 Amsterdam Internet Exchange member's main websites, 9 are
reachable over IPv6 (up from unknown / 4 just under a year ago)
- of the 213 Amsterdam Internet Exchange members, 59 had an IPv6
address enabled on (one of their) port(s)
Would you let us know how you were able to collect such statistics ?
Simple: fire up tcpdump -p ip6 and port 80 and then visit
http://www.ams-ix.net/connected/ and start clicking. For the top 100
list I found something that I'm sure isn't the actual top 100 list but
for my purposes that doesn't really matter.
