@ Tom Good point about the reduction in pricing with regard to internet access slowing due to upgrade costs, and I wonder how Teleco's will handle this opportunity to reduce the pricing of their service if as Curtis mentions they can leverage IPV6 faster than everyday networks can ....
Amazing. Well, we seem to have run to the end of our time here. Tom, thanks so much for giving us so much of your time today -- it's been great, and we look forward to talking with you again in the future!
@tomdynic is that timeout going to cause issues in the future when more people are requesting IPv6 addresses and you're not responding or will the IPv4 interface just take off when it gets a response without waint for the IPv6 interface?
@Curtis: You'd think - but they are two seperate networks, and we all used to think we'd have an IPv6 "flag day" to just turn it on. No one thought about us doing billions of dollars of commerce over the Internet at that time.
@Technocrat @The_Phil And I would bet you some $$$ that the issue was raised due to some interaction between IPv4 and IPv6, and likely their ability to look up their hostname records in DNS via v4 and v6. The ability for systems to detect if they are connected to v4 or v6 or both has been a long problem.
@Curtis: No joke! Newer devices, such as iPads and tablets are supporting IPv6 out of the box, and it does "just work." Like anything else, implementing IPv4/IPv6 from nothing is far easier than trying to graft IPv6 support onto an IPv4 system.
You know, I do think it would be funny (in both an ironic and a "ha-ha" sort of way) if my phone and tablet devices were operating on IPv6 before my laptop computers...I wonder whether phone companies will be early movers on this because they don't have to worry about firewalls and routers on the customer end.
And @Tom, I figured that DNS would be fairly solid -- something told me that you'd have things moving in the right direction over at Dyn!
@zerox203: They might. It takes a lot of money to upgrade networks, and some ISPs never planned for these upgrades in thier business models. It's why we've seen a slowing in the compression of price for Internet access recently, these networks have to pay for these upgrades somehow.
@tomdyninc, but are we giving the ISPs too much of the benefit of the doubt by saying they 'cannot upgrade'? I'm afraid some of them might end up trying to use stopgaps longer than they should, out of something other than neccessity.
@Curtis: I'd say that the protocols in IPv6 and related services are laid out at this point. The design is done, but for many services, such as IPv6 DHCPv6, the implementations are fairly new. This has created some hold ups in the adoption and deployment of IPv6.
@Tom, I've also seen some questions about whether some of the basic network functions (DNS, DHCP, etc.) have been "standardized' in IPv6 functionality. Is that an issue? I know at least one vendor that was holding off on updating hardware because of an IPv6 DHCP question, for example.
@Curtis: There are many different transition technologies out there: 6to4, Toredo, 6RD, DS-Lite. They are simply ways to provide IPv6 to the edge of carrier networks, across an IPv4 core. There's lots of implementation differences, but they all accomplish the same goal of getting IPv6 connectivity to users.
@Technocrat: Good question. You might have an IPv6 address locally, due to something in IPv6 called Stateless Autoconfiguration (SLAC) in IPv6 - it's kind of like DHCP for IPv6 lite edition - if the devices in your network support it, you may have an IPv6 address. Whether or not you can get out of your network on IPv6 is another story.
@LadyIT, I know that I've seen performance differences when I go to IPv6 sites now -- Google, YouTube, and several other sites have IPv6 version -- but I think that's probably because of a difference in user load rather than any inherent difference brought about by addressing.
One thing that I should point out to everyone: The IPv6 Internet is still being built - people need to implement it to it to get it to work across the Internet - one of the key problems today is that one IPv6 user may not be able to connect to another IPv6 user if those two independent networks are not connected.
The_Phil: Sure, you setup your services on IPv4 and IPv6, and watch / compare your log files. It's a lot of data crunching, but it is the only way to make sure things are working properly at this point.
@Tom, I see. While I know that's a good idea from a security point of view, I wonder if governments like the one that seems about ready to relinquish power in Egypt will be more active in forcing their countries to IPv6 for "national security" reasons. They'll certainly want to know who's saying those nasty things about them in chat sessions...
@Curtis: We certainly get more security - we'll know exactly who was doing what with what addresses and when - no more hiding your true identity behind NAT. You're also right in the that it is largely dependent on what vendors choose to do.
I'll throw out to everyone that, if you want to see what your current IPv6 status is, you can to to http://test-ipv6.com . The results are fascinating, and can show you some things you didn't know about your ISP's service.
@Sara: The only way to know is to test. Setup a small version of your website on IPv6, and see who can get there. Many websites today use a tracking pixel devliered over IPv6 only in their HTML to see if a user is connected to IPv4 and IPv6. Check out http://ipv6.google.com for an example.
@Tom, I can see that, but I keep reading stories that say that IPv6 is bringing major new security functionaily to the table. Is that true, or does it depend on what the hardware/software vendors choose to do with the capabilities of IPv6?
@Technocrat: You're right, its a mix. It really depends on the hardware and software. Some software based devices, such as home routers and gateways, will only need new software loaded onto them. For hardware based devices, such as large core Internet routers, which handle 100s of Gigabits of traffic, run IP addressing right in the hardware, in the silicon. In many cases, these hardware devices need to be completely replaced.
@tomdyninc You say: You should be thinking about what services you need to expose to your customers and users that makes sense. As a service provider, think about who is accessing your networks, and what type of transport, IPv4 or IPv6 will they be riding over." How can I best determine what type of transport my customers will be riding over?
@DBK it's going to be market demand. I know the manufacturer of my firewall has been "conservative" with their IPv6 implementation -- they're only now issuing firmware updates that start to deal with things like IPv6 DHCP and firewall rules.
In IPv6, we know that security gets harder. There's much more address space to secure, and there's many hurdles to managing the address space. Without NAT in IPv6, I do worry that more home users will go ride on the open internet, without the use of a firewall to protect them.
@ Tom Some say manufactures will provide upgrades for hardware that needs to be reconfigured for IPV6 ? Some say it is not necessary - and some still claim you will need new hardware. What is the real answer ? A combination of all of these ?
@Sara - Not really. You should be thinking about what services you need to expose to your customers and users that makes sense. As a service provider, think about who is accessing your networks, and what type of transport, IPv4 or IPv6 will they be riding over.
@ LadyIT I have heard that IPV6 will allow enough ip addresses to assign one address to every strand of sand in the world ...whether it is true or not ...who knows.... but being based on 128bit structure surely gives it a good chance of lasting our lifetime at least.
I think that there have been discussions at ICANN/ IANA that we move to IPv6, and create new top-level domains -- for nations. or for different types of businesses that require different security postures

Skype/Outlook UC integration means we're going to have competition and fragmentation of UC client architectures, but is that bad? Modern devices can support IM, email, voice, and video clients, so maybe it's the back end of UC we need to be worried about.
Workers are now used to portable device support throughout their everyday lives. We should be looking at the policy of providing fixed-desk devices to support stationary workers. Could portable support be smarter?
Input devices run the gamut, from the humble Missile Command-style trackball to advanced speech recognition. Unfortunately, these input devices can be used for evil as well as good. Case in point: mobile ads that want you to talk to them.
