More than 200 organizations around the world
turned on IPv6 at 12 a.m. UTC on June 7 for the world’s first mass test
of the second-generation networking standard.
Participating Internet service providers, content
management networks and Web companies switched to IPv6 networks for a
24-hour test to increase awareness as well as to work out the kinks in
the protocol at 8 p.m. EST on June 7. Participating organizations are
not limited to just technology companies, as government agencies,
educational institutions and entertainment companies are also taking
part, according to the Internet Society.
For most users, it is business as usual
and nothing will be obviously different. For others trying out the
latest thing in networking technology, it is quite entertaining.
Armed with a Windows 7 laptop with an IPv6
address, eWEEK started browsing the Web to see what was happening on
World IPv6 Day. Instead of having some parts of the world start earlier
or later than others, the switchover is happening more or less
simultaneously, using London time as the cut-off point.
“Everyone is turning IPv6 on and off at the same time,” Andy Champagne, engineering vice president at Akamai, told eWEEK.
Some companies appear to be having some fun with
IPv6. Eagle-eyed Web surfers will notice that Facebook’s address
2620:0:1:c18:0:face:b00c:: contains a mis-spelled version of its name
(face:b00c). Cisco’s 2001:420:80:1:c:15:c0:d07:f00d address reads
‘Cisco dog food.’ Dog food is a tech term to mean the company is using
its own products.
While browsing for IPv6 Websites, what was more
noteworthy were the number of major technology giants who chose not to
enable IPv6 on their main Websites, such as Comcast, Intel, AMD and
Apple. While Level 3 Communications, a Broomfield, Colo.-based Internet
service provider who operates a Tier 1 network, had an IPv6 address,
the site level3.com initially returned a 404 “Not Found” page. Level 3 had an IPv6 Website up for about a year but had a slight "hiccup" when switching configurations, but resolved the issue within hours, Jon Paul McLeary, a Level 3 spokesperson, told eWEEK.
There doesn’t seem to be much of a hitch getting started. RIPE
(Réseaux IP Européens), which is the regional Internet registry for
Europe, is tracking specific organizations to measure their
participation. Several of them, such as the United States
Department of Commerce, Ericsson, and Mozilla appears to have enabled
IPv6 long before the official switch time. RIPE’s chart measured
whether user clients could find each listed organization’s IPv6
address. Mozilla appeared to have a bit of a hiccup about a half hour
into the test, with some of RIPE’s test machines failing to find
Mozilla’s Website.
Many organizations are participating in World IPv6
Day without having actually made any changes to their networking
environment or Website, thanks to Akamai. The content delivery network
signed up 30 customers from around the globe, about one percent of its
customer base, to its Akamai IPv6 Service, Champagne said. The service
allows customers who don’t have IPv6-enabled Websites to still be
accessible to users browsing the Web using machines with IPv6 addresses.
The differences in the IPv4 and IPv6 standards
mean that the two address spaces are generally separate and cannot
overlap. That means users with IPv6-enabled devices can’t access
Websites hosted on servers with IPv4 addresses, nor can IPv4-enabled
devices access sites hosted on IPv6 servers. Dual-stack configurations
and tunneling services have been used to help bridge the two parallel
networks. Akamai’s service is another method customers can use,
Champagne said.
With the service in place, users can “talk” IPv6
to Akamai, who translate the network request to the customer’s
IPv4-based Website, according to Champagne. The service is intended to
help customers who core competency is not in technology. They don’t
need to invest in the networking equipment or hire IPv6 experts to
participate in the IPv6 test or to make the switchover.
An example appears to be the United States
Treasury Department. The Treasury.gov Website is hosted on Amazon
Elastic Compute Cloud servers, which currently does not support IPv6,
but the site is accessible over Akamai’s service. The IPv6 address
2a02:26f0:c:1::5c7a:32b1 that comes up when looking at the site is part
of a subnet owned by Akamai, according to the latest Whois data.
Akamai has a data virtualization tool
on its site that shows how much IPv6 traffic is accessing the Websites
belonging to the 30 customers signed up on the IPv6 service. On
average, there have been about 208 IPv6 hits per second, three hours
into the test. Akamai’s network saw a surge about a half hour after the
switchover, with about 458 hits per second, as curious Web surfers
checked out what was happening.
