strech IPv6. This is why, for World
IPv6 Launch Day, we took a check of a tip 20 ISPs in a US to see where they were with their
IPv6 support and rollouts.
Which tip Internet use providers support IPv6?
To establish a tip 20 Internet use providers, we gathered a list of a largest and most
commonly listed Internet use and communications providers of a United States. While this
methodology excludes smaller IPv6-savvy ISPs, like Hurricane
Electric, we entice comments from any
organization that believes it should be mentioned in a survey, supposing they answer a following
questions:
- Do we support local IPv6 entrance for craving customers?
- Is your homepage permitted around IPv6?
After compiling this list, we examined a websites of any ISP; where IPv6 information was not
available or displayed on websites, we called and questioned tech support staff about support and
professional
services for IPv6 migration. In further to sleuthing for answers on local IPv6 access, we
visited a websites of any ISP on Jun 5, to see possibly their homepages were IPv6 accessible,
and we checked possibly a ISP was a listed on a World IPv6 Launch Day pages as an IPv6-compliant website
(including both Website Operate and Network Operator member pages, regulating both organization
name and primary site URL searches). In this investigation, we found that some companies claimed to
be IPv6 agreeable nonetheless didn’t exam as such as of Jun 5, 2012. Even some-more interesting, a surprising
number of tip Internet use providers indeed offer IPv6-compliant websites even nonetheless they
won’t nonetheless divulge their IPv6 support skeleton for customers. In one box (Comcast), one of their
domains was IPv6 agreeable (.net) while another one was not (.com)!
As we will see in Table 1 below, some ISPs have homepage and local IPv6 support; others are
almost ready, while others are not prepared during all. In a startling array of cases, we couldn’t find
out online or by phone possibly they now support IPv6. In a list cells, a phrase
“information not permitted (INA)” means we searched for answers to a questions above nonetheless received
no response from a organization’s tech support staff. “Transition skeleton not available” means the
organization has skeleton to make local IPv6 use permitted to some or all of a business at
some indicate in a future, nonetheless isn’t prepared to speak about them yet.

At a time of this writing, it seems utterly transparent that all of a tip Internet use providers
are thinking about IPv6. But maybe usually half of them will support IPv6 today, and more
than half possibly can’t or won’t divulge their IPv6 skeleton during this time of open awareness. On the
flip side, it’s also really revelation that usually 4 companies of a 20 we polled here –
namely, ATT, Comcast, Charter Communications, and Clearwire/Clear — indeed explain to support
IPv6, and that usually 6 had their home pages permitted around IPv6 5 days before IPv6 launch day
is scheduled to take place.
