Expensive network infrastructure, lack of benefits for early trendsetters, and end-user tech incompatibility play a significant part in the developmental delay. Being able to support IPv6 requires extensive bare-metal and other infrastructure resources — not all internet service providers ISPs and telcos are financially capable to make the investment. Hence, the development pace relies mostly on major market players. However, without the small to medium sized enterprises SMEs in the equation, the industry is at a loss of a substantial part of organisations that could help speed up the IPv6 implementation process.
Limited funds hinder the transition process, but the ones that cannot afford the switch still need market-ready solutions to continue scaling. The problem can be addressed with IP address leasing , as it enables leasing out unused IPv4s, providing a more timely solution and facilitating the transition to the next phase.
Transition to the new protocol comes in two phases: first, the adoption of dual-stack services, where both Internet protocols are used simultaneously, and second — full IPv6 transition. Certainly at work we have a couple layers of different types of firewalls. I'm absolutely not saying that pe.
You can easily have a default stateful firewall that does exactly the same thing: Block all incoming connections, allow all outgoing connections. You can't "transition". You can and should run dual-stack to help make an eventual transition possible. We will get rid of IPv6 right about the same time we get rid of Cobol.
Probably not never, but much longer than years. That is my guess anyway. Go ahead and move your networks to IPv6, just make sure your users can still ping IPv4 addresses. I would but I get half a second of latency from the backbone as punishment, since they want to advertise the capability but don't have the routers for it. It's already taken 22 years so far because the draft standard was established in That's already more than "5 to 10 years".
That's not how relative timescales work. The length of the past has no influence on numbers you give in the future, the English language simply doesn't work like that. In English it depends on the words used. In this case it describes a continuous tense with a beginning and end, and the beginning can be in the past or future depending on if the activity has begun yet.
The question is about the amount of time that comes between the beginning and the end of the activity. If the question was about the future, it would be how much longer will it take. Not "how long. When I got it, I was under the impression that the transition had already begun and that it would be useful. So it seems like an easy question. I wonder if they'll ever manage it? Maybe if we Balkanize the internet we won't need it.
It's up to amazon, microsoft, google, ovh, linode, and other cloud providers. Everything should be IPv6 first at this point. Comcast still won't offer static allocations of IPv6 space in many markets for business customers. I wasn't aware of this but I have to ask why you need a static allocation if you can use dynamic DNS? And from what I have seen from Comcast is that my IPv6 address at home hasn't changed in four years. If i did have a DNS authority for my site it wouldn't have to register an update very often.
A tunnel will not have the same performance as a native IPv6 allocation. There are servers that do not benefit from dynamic IP addresses such as DNS itself, service monitoring, and configuring switches or routers for specific hardware to have access to specific privileged VLAN's.
The cloud providers generally do provide IPv6. We make products that use IPv6. As such we used IPv6 internally a lot, once IT got used to it, especially internally and on lab networks. Later we got acquired by a larger company and now so many things are IPv4 only, even many labs. It takes a bit of getting used to going back to IPv4 in a way, even though the addresses are smaller they don't resemble the MAC address of the devices and you can't determine what add.
To be fair, they have been supporting it, what they haven't for the most part been doing is encouraging IPv6. The result is that our IPv4 infrastructure suddenly became accessible to those only using IPv6. Before that, Amazon's AWS had similar features for its load balancers, but they weren't enabled by default. And while I didn't play with our Azure hosted websites, I never saw an IPv6 address ever resolve for them either, Microsoft certainly wasn't encouraging IPv6 or making it transparent.
In the end though, the biggest problem I'm seeing is that system administrators have no idea what IPv6 is or how to support it properly. In the IPv4 world, we have internal networks that use NAT and dedicated internal IPs, and that's because we can't get enough IPv4 addresses, but we like to pretend it's somehow superior and is done for security reasons.
But in reality we're undermining our security, because we don't put enough in to secure computers on internal networks from one another, and we have to route every peer-to-peer application through third party proxies think of all the video conferencing crap we've been having to do routed via Zoom, Google, or Microsoft recently, as an example, I'm not talking about obscure applications any more that can snoop on everyone, and can fail easily, because traversing NAT isn't practical.
In the IPv6 world, we don't need to do that any more, every computer can have a routable IP address, and by doing so we unbreak many of the protocols and applications that NAT breaks. As for security, we now have to do it properly, and use application level firewalls, IPSEC, etc, but what's wrong with that? No longer is the office network compromised because a consultant came in with a compromised laptop and plugged it in. Why aren't we doing it? Because it's new, and system administrators who are already brain fried by having to learn Active Directory are uncomfortable with the switch to a whole new paradigm.
But yeah, if you're in this boat and you don't want to be at least part of the problem, see what you can do to add an AAAA address for every A address your externally accessable websites have. And if you can't do it yourself, get Cloudflare or someone similar to do it for you. The serious answer is that inside vs outside the local network are two very different things. Inside almost doesn't matter. There will be legacy devices on the LAN and the need for dual stack for a long time to come.
But this is also a self-solving problem so not even an issue. I did switch over my home workstations and servers to IPV6. I did it because I was interested to see if it made any difference -- it didn't. Here's how I'd make the transmission happen: I'd start taxing globally routable IPv4 address space. You would hit the wrong people if you're not careful. Way too many are using v4 because that's all that's on offer.
I would love to hand back every v4 address I control, but if I do that now, too many things outside of my control will break. It's really the slow entrenched older ISPs that are causing all of the problems not deploying IPv6 to the end users.
I'm not sure I buy this statement. Heck, it's one of the few things I'll praise Comcast for. My evidence is anecdotal, but after talking to a lot of friends who are doing IT at various levels at all sorts of companies - I think a lot of companies are the problem.
They certainly have IPv6 on their web servers, although they're not hosting those on their own networks. But, i. People take an attitude of "ipv4 is working for me" and don't care about all the problems it causes for others Developing countries are stifled because they can't get the huge ipv4 allocations that developed countries have, users in these countries end up being stuck behind multiple layers of nat so they're not part of the internet - rather just outside observers with second class connectivity.
No hosting of your own services, no p2p, having to rely on third parties to relay your communications and all the latency, performance and privacy concerns associated etc. A lot of time and money is spent working around the limitations of ipv4 too, addressing is expensive, implementing cgn is expensive, correlating logs when addresses are translated is expensive. Doing away with all this crap would be hugely beneficial for a lot of people and organisations. There are many advantages to ipv6, but far too much ignorance and laziness out there.
I can't emphasize this enough. I recall when I first started using IPv6 about 5 years ago once I had configured my first systems my reaction was why the hell did I wait so long. My first Linux system took me about 90 minutes to do. About 20 minutes of that was reading How-To articles, about 30 minutes making mistakes in configuration files, about 15 minutes learning how to use AAAA records. The second Linux system took about 5 minutes. As did every one after that. What benefit, precisely, did you get from IPv6?
Besides helping you feel like the cool kid after wasting an hour or two of yout time that you will never recover? I could understand some benefit professonally from learning about it on your home network, I suppose. I have a small cluster of servers each running a variable number of VMs in a co-hosting location. The site provides full IPv6 support and a static allocation. They also give me a block of 16 IPv4 public addresses. If I want more I have to pay for them. Oh, there are many viable approaches to support this.
While you may understand the greatly increased security requirements of such a configuration, that should absolutely be discouraged for regular consumer use. First they have to find a v6 address with anything actually behind it before they can even start guessing. With v4, any address they might try is very likely to reach something. Of course, there's always scraping DNS for live addresses, but that's yet another brute force step before they can brute force a password.
I can't speak for OP, but my Comcast v6 prefix is routable and unfiltered. Not a lot to configure for me, I just enabled it on my router. It was nice to not need a 6to4 tunnel at home anymore. Actually large swaths of global enterprises operate quite nicely behind layers of NAT. Might you be claiming THEY are only outside observers? IPv6 is the latest version of the Internet Protocol, which identifies devices across the internet so they can be located.
Every device that uses the internet is identified through its own IP address in order for internet communication to work. The previous version, IPv4, uses a bit addressing scheme to support 4. However, the growth of the internet, personal computers, smartphones and now Internet of Things devices proves that the world needed more addresses.
In it created IPv6, which instead uses bit addressing to support approximately trillion trillion or 2 to the th power, if you like. Instead of the IPv4 address method of four sets of one- to three-digit numbers, IPv6 uses eight groups of four hexadecimal digits, separated by colons. The IPv6 protocol can handle packets more efficiently, improve performance and increase security. It enables internet service providers to reduce the size of their routing tables by making them more hierarchical.
That way a corporate machine with a private IP address can send to and receive packets from machines located outside the private network that have public IP addresses.
Without NAT, large corporations with thousands or tens of thousands of computers would devour enormous quantities of public IPv4 addresses if they wanted to communicate with the outside world.
