The overall connection numbers were a bit worse than non-anycast sites, but they still indicated similar performance between IPv4 and IPv6. Another tie at the end. We ran these tests without knowing what to expect, but were happy with the results and can confidently say that IPv4 and IPv6 performance are pretty much equal.

IP6 gives you more IP addresses in a network not really useful for households with less then devices.

Skip to primary navigation Skip to content Skip to primary sidebar Skip to footer IPv6 usage has been growing very slowly through the last 10 to 15 years. This breakdown of connection failure rates by address type is shown in Figure 4. The data analysis was repeated over , looking again at connection failures. The comparable data on overall connection failures is shown in Figure 5. Figure 5 — Connection Failure Rates by protocol — The data for IPv4 is not complete for the entire period, and there is no packet capture data for IPv4 in the period September — October.
There is also a visible discontinuity in the data for IPv6 on the 1st September. The advertisement platform ceased support for Flash as of 1 September and the change to an all-HTML5 profile changed some of the relativities of the IPv6 systems being used for measurement. The IPv4 connection failure rate shows a steady decline over the year Figure 6.
The connection failure rate by mid November was 0. Four years ago the poor IPv6 connection performance was largely due to the prominence of the use of Teredo, which had an excessive connection failure rate, and was helped by the widespread use of 6to4 which was not all that better. In the intervening four years Teredo has all but disappeared, due largely to a combination of successive releases of Windows systems effectively deprecating Teredo and the withdrawing of the Microsoft-operated Teredo relay services.
Figure 7 — Connection Failure Rates by Day — If we discount the 6to4 connection failures, then the resulting profile is an average connection failure rate of 1.
The comparable number for IPv4 is at 0. There are perhaps two lessons to draw from these measurements. The first is that, in general, IP tunnels are not the best idea to have. The second lesson is that there is a large amount of largely forgotten unattended devices out there on the network that are causing issues. It appears that most of what we are seeing in unicast IPv6 failures is network equipment that is not working in sync with its end client base. It is likely in many of the failure cases that endpoints assume that they have IPv6 connectivity and emit an IPv6 packet, but a filter in the network is configured to block all incoming IPv6 packets.
The second aspect of relative protocol performance examined here is that of relative network path delay. The set uses a common unique DNS name component, allowing association of the common unique name component with an IPv4 and an IPv6 source address for the endpoint. What we have is two measurements for the RTT between the same two endpoints Figure 8.
There are a number of reasons why these two RTT values might differ. It could be that the network paths may differ between the two protocols. This is going to be the case when the IPv6 connection uses 6to4, as 6to4 involves a third party tunnel relay, but even with conventional unicast IPv6 and IPv4 are routed as distinct protocols and different network paths for IPv4 and IPv6 are not unusual.
Even when the two paths are precisely the same, the RTT measurements may differ slightly. Older routers passed IPv4 packets through an optimised switching path, while IPv6 packets were switched by passing the packet through slower software based processing.
This is far less prevalent today, but may still be the case in some instances. In fact, it may even be faster in those cases. Why is that larger header not as much of a factor as you think?
That's because the designers of v6 took some of the lessons of v4 and built things better. Most importantly for cross-internet communications the address fields are handled much more efficiently in routers than in v4, which improves speed of v6 packets through routers as compared to their v4 cousins.
When it comes to same subnet communications where router tables aren't a concern, each packet requires less raw computation. And on special networks, the ability to have VERY large packets can further save processing. You might see performance improvements with IPv6 if there is a slow router between you and your destination which would have fragmented IPv4 packets along that path.
With IPv6, routers will no longer fragment packets for you. Of course, this is an edge case. There is no reason to believe IPv6 will perform better than IPv4 in the general case. Also, router vendors may also have optimized their IPv4 data paths more than their IPv6 data paths.
So until IPv6 routers have equivalent optimizations, IPv6 may be slower. For example, some routers may do IPv4 routing in hardware, but IPv6 in software. High-speed performance tests would have to be done to identify this. So you have to weigh the chances that there is a router that isn't optimized for IPv6 between you and your destination with the chances that there is a router doing fragmentation of IPv4 packets between you and your destination.
I can tell you that most of the time the performance and latency are about the same. But on occasion, IPv6 will make your jaw drop. Nearly identical. That's what I see most of the time. But every so often, such as when I'm accessing one of my own servers, which is also on IPv I suspect there are lots more of these out in the wild.
In my experience of comparing traceroute6 vs. This is probably because IPv6 generally requires fewer hops to get from point A to B. No, there would be no speed gains to speak of, although routing tables are certainly made simpler.
To say that IPv6 "just" makes more room on the net is like saying the Milky Way Galaxy "just" makes more room for dust grains.
IPv6 essentially makes it so that it's literally impossible to run out of IP addresses. Please fill in the form below and we will contact you within 24 hours.
What is IPv4? IP stands for Internet Protocol. It is a numerical label assigned to each device in the given network. What is IPv6? Furthermore, there were issues with IPv4 that had to be resolved but the existing IPs could not have changed. It is a complete numeric address and the bits are separated by dots. IPv6 is the most recent version of IP. The address is a combination of alphabets and numerals, called Alphanumeric, and the bits are separated by colons :. IPv4 allows a definite number of IP addresses classes, which has been a persistent issue.
The classes are numbered from A to E. IPv6 can have an unlimited number of addresses. One of the greatest downsides considered with the use of IPv4 is that the network needs to be configured manually or with DCHP. This really limits the level of automation that can be achieved while using IPv4. IPv6 has provisions for supporting auto configuration, which is considered one of the major improvements over the IPv4.
Compatibility with Mobile Devices Because IPv4 uses the dot network it is not suitable for mobile network and thus IPv6 is the only choice when rendering IP to mobile devices is the essence.
NAT takes private addresses and then turns them into public addresses. NAT is what enables a corporate device having a private IP to communicate with public devices. Private IPs are confined to a private network and enables one device to identify the other within the network. When one these devices need to communicate with an external network or another device outside the network, it does so using NAT, which assigns it a public address.
Which is faster IPv4 or IPv6? IPv4 vs IPv6 stack almost equally against each other when it comes to speed. Relax, we have you covered.
