What's Your Timeline for IPv6 Migration?
SgtChaireBourne asks: "IPv4 has, over the last 20 years, seen unexpectedly wide adoption. During this time it's proven to be both flexible and robust, but also several problems, though once small, have grown. IPv6 looks to solve some scalability problems, add needed privacy and authentication mechanisms, address quality of service, and provide better routing and addressing capabilities. What kind of timeline does your site/institution/business have for rolling out IPv6 and how?" Those interested in IPv6 migration may also be interested in this article, from a year ago.
"Nobody else is, so why should we?"
That's basically the position we've taken for some reason where I work. Sure, we've been toying with grabbing a block and deploying it on some of our core routers across North America, but...there's no real need per se to do a serious deployment. Nobody's been asking for IPv6 either.
Maybe if there was a way to have mandatory conversion, things would move along a lot quicker.
In today's business climate, we can't imagine migrating without a financial incentive to do so.
IPv6 is like BetaMax tapes back in the 80's: sure, the format is technically better, but we've already got a ton of IPv4 gear and software. Even if you only use free software, there's still man-hours involved for implementation and planning. I pity the fella who walks into his boss's office and says, "Yeah, I'll be spending the next week on the IPv6 migration, getting all the desktops working, upgrading our router firmware, getting an IPv6 address from our ISP, etc."
IPv4 will work just like VHS tapes did: it'll be fine until the next dramatic quantum-leap comes along, like Tivos and DVD recorders will cut down on VHS recorder sales. IPv6 has some neat features, but nothing that a typical small business can't live without.
In the go-go-90's, you'd have been able to pull it off, but these days, if it ain't broke...
What's your damage, Heather?
I've already switched, but isn't it more important whether all the really huge backbone servers switch? I mean, the majority of them are using IPv4, so are they willing to shut down for a few moments to upgrade (assuming it takes that long)? If they switch, could that entail major loses in their companies income?
I'm thinking that it'll really start to get to the point where I will start using it in 2008. This is me speaking about my small hosting business as well as a member of the local Internet Cooperative. I'm sure I'll be playing with IPV6 in the next year or two to get up to speed on it.
At the moment you can't get IPV6 service from any of the large providers. And really only people on ipv6 can take advantage of it, so... Until a significant portion of the end-users have IPV6, I can't see that we'll have any real need to start using it in any real way...
It's, obviously, a chicken-and-egg thing. It was really pushed because of the "sky is falling" shouts about running out of IP space. Todays world seems like there's plenty of IP space, if you're not super wastful with it, and we have other problems to face like router table space and ASNs.
The other problem I don't think we really have ironed out right now is that the routers are really underpowered and optimized for ipv4 routing. I expect that having significant traffic on IPV6 is going to stress many of the bigger routers on the net to the point that they can no longer function. Lots of "big router" admins are already working hard getting the routers to handle current traffic.
