One Year After World IPv6 Launch — Are We There Yet? 246

Posted by samzenpus from the state-of-things dept.
darthcamaro writes "One year ago today was the the official 'Launch Day' of IPv6. The idea was that IPv6 would get turned on and stay on at major carriers and website. So where are we now? Only 1.27% of Google traffic comes from IPv6 and barely 12 percent of the Alexa Top 1000 sites are even accessible via IPv6. In general though, the Internet Society is pleased with the progress over the last year. '"The good news is that almost everywhere we look, IPv6 is increasing," Phil Roberts,technology program manager at the Internet Society said. "It seems to be me that it's now at the groundswell stage and it all looks like everything is up and to the right."'"

      This myth again - you should know better. Nobody is suggesting removing the firewalls that can prevent the constant external vulnerability scanning of any host directly connected to the Internet. They can do it quite well without the utter pain in the neck that is NAT. Yes, NAT saves newbies arses, but so now does the default configuration of even cheap and nasty ADSL routers so taking it away probably will make zero difference.

      They _do no tneed_ a different IP address for their email server, their FTP server, their web server, their phone server, their chat server, and their IRC server.

      Are you seriously making such a suggestion in 2013 when we are knee deep in virtual machines or are you joking? It doesn't take much complexity before you end up wanting to have two separate things running the same service and then you've got to do some arcane mucking about with non-standard ports and port forwarding if you've only got one real IP address. You've also got to be sure that the ports you've chosen are not being blocked at the other end and that can very seriously limit your choices, to the point where people connecting through mobile/cell networks have to be allowed all the way in to an almost unprotected network by VPN since you have run out of ports the telco allows. In such a case NAT becomes the security risk instead of the security solution you are trying to convince the gullible it is.

      Nobody is suggesting changing that. You still get all that filtering only without the constriction of NAT.

        Yes, it really does. Many of the groups I work with are staffed by newbies, even in their IT departments. Maintaining Internet exposed firewalls is as fragile, and dangerous, as handling electrical power directly off the power grid before it's been stepped down to 120 Volt. Errors are very common, and profoundly dangerous. It should be avoided by anyone who doesn't absolutely need it

        > Are you seriously making such a suggestion in 2013 when we are knee deep in virtual mach

        • No, I'm suggesting that in 2013 we have load balancers and proxies that do an excellent job of distributing exposed services to arbitrary numbers of internal hosts. The hosts generally have no need, or excuse, to be exposed directly to the Internet. Therefore they do not need a routable IP address. There are a few services, such as SMTP, that deal well with multiple available public IP addresses. And there are some web services that deal very well with multi-homed IP addresses in multiple physical locations. Google is an excellent example of that.

          But that is precisely what IPv4 is running out of - having multiple available public IP addresses. Even for NAT, when they do Port Address Translation, they prefer to have more than 1 public address for the purpose, especially for load balancing. This is the very thing that IPv6 addresses so well that the need to have NAT disappears.

          Also, it is a good idea to have separate routable IP addresses for different virtual machines, as well as for imap servers, smtp servers, ftp servers, web servers, irc ser

      A simple stateful firewall will mitegate the dangers of scanners just as well as a NAT. In fact, the extensive address-space in IPv6 actually makes scanning much less effective since the vast majority of the addresses a scanner is going to try aren't even in use.

Many home users cannot afford to upgrade their hardware and software on a whim and won't have a budget to do so for a few more years (mostly due to slow economy and unemployed consumers). I suspect it will take five to 10 years before we start seeing IPv6 make its way into mainstream services.
