This means that during migration, mechanisms must be put into place that enables communication between IPv4 and IPv6 networks. Designers and engineers opted to completely redesign the architecture of the protocol to deliver the required performance and capabilities, resulting in two mutually exclusive protocols. For example, Wi-Fi 6, which is defined by the IEEE 802.11ax standard, is backward compatible with previous iterations of the technology, including 802.11g/n/ac.Ĭonversely, IPv4 and IPv6 are fundamentally incompatible. When new protocols and technologies are developed, many maintain some level of backward compatibility. This, along with several innovative and very effective technologies such as NAT, has suppressed and delayed the need for migration, greatly slowing the transition process. And remember, IPv4 isn’t going anywhere anytime soon, so expect it to be around still when it enters its sixth decade of existence.Īrguably, IPv6’s greatest enemy is IPv4’s great design. Rarely will you find telecom protocols with such longevity. The reason for IPv4’s successful operation for over four decades is simply the fact that it was designed so well. If you were surprised that IPv6 is around the age of a young adult, you might be astonished to find out that IPv4 is comparatively middle-aged, having been first defined in RFC 791 in September of 1981. OK, there are some technical obstacles that have contributed to the relative delay of IPv6 adoption, so let’s start with these first. I’d like to showcase some of the most prominent obstacles in an attempt to help you understand them and to be able to overcome them more easily in your particular implementations and experience. There are many reasons for this, and the unexpected truth is that many of the most significant are not technical. IPv6 has been around for almost a quarter of a century (an eternity in telecom years) and has yet to surpass the threshold of a 40% adoption rate on the Internet, according to Google. These are not all inherent to IPv6 itself but also to a series of seemingly unrelated factors that, together, form the main resistance against IPv6 adoption. The original protocol was defined in RFC 2460 way back in December of 1998! That means that at the time of this writing, IPv6 is turning 22 this month!ĭespite its significant improvements, its vast scalability, as well as its expected longevity, IPv6 still has several noteworthy challenges that must be overcome when transitioning from IPv4. That was twenty years ago!Īnd yet, IPv6 is not as young as we may be led to believe. It was then that I first started studying to get my CCNA certification, and of course, the focus of the content, at least as far as Layer 3 protocols go, was indeed IPv4.Īs I think back, I don’t even remember if I was even vaguely aware of the existence of IPv6 at the time. Not much you can do when a undersea fiber gets cut and you are on a backup network.It was just about twenty years ago that I began delving into the world of networking. ISP monitor their network and generally see issues and fix them if they can. Other stuff you would have to get lucky take to a ISP. Your really can only realistically fix hop1 (your equipment in your house) and hop2 (the connection to your ISP from your house). It not like you can call them up and complain. What can you possibly do about it if that router is owned by say google or maybe level3. The bad news is lets say you see a issue with HOP 6 that continues to the end IP address. Next you need to do tests to the actual game servers since the path to them is different. There is almost nothing that only runs on IPv6. So first I would turn off IPv6 in your machine nic settings. No matter how much they say IPv6 is the s been 25 years they say that.many ISP still do not have as good pathing for IPv6 as IPv4. This is also partially done to prevent denial of service attacks against a router. The reason you see loss to intermediate routers is equipment is generally configured to favor actually passing data than responding to test ping packets. You can not have issuers in the path and it not actually cause issues on the final destination. If 80% of the time you drive though a intersection you get a new dent it means you still would have those dents when you get to your destination. Lets say the hops were intersections on way to work and packet less was big rocks hitting your car and putting dents into it. Everything you see is a result of the testing method and not actually any problems. This is why people need to do ping and tracert by hand rather than depend on apps they click one button.
