I still can't get away from this sensation that no matter how good IPv6 is, the ship has sailed. The inferior but indisputably cheaper technology won out over the technically superior one. VHS vs Betamax. Ethernet over Token Ring.

The original RFC came out in 1995, the modern RFC used today in 1998 - almost 25 years ago. When I was in college in 2012 (going through the Cisco NetAcad) they were preaching that our IPv6 future was "just around the corner". I am going on 10 years in network and security now, and I still don't see it. At least in the US, IPv4 is, and will remain, the dominant force. There are many reasons for this, but one of the b…

As of I'm writing this google sees 50.03% of its traffic on v6. According to https://www.google.com/intl/en/ipv6/statistics.html

Maybe dominant is the wrong word, large might be better.

IPV6 becomes supercharged when you layer it with the original Bitcoin protocol. It integrates Cryptographic Generated Addresses in IPV6 which is an extension that has been around for awhile but never implemented. Here is the founder and chair of the IPV6 forum giving a speech about it just a couple of weeks ago: https://www.youtube.com/watch?v=dE3Vsbo1NPs Really cool engineering things are being worked on in the back…

Think a new IP address for every packet.

Think on solving BGP vulnerabilities through micropayments.

Originally, Bitcoin had no limits in place including the block size. That was added later.

The original protocol scales to trillions of transactions per second. The secret is the Merkle tree and the block header. The block headers only take up megabytes and are easy to keep track of and distribute.

Simplified Payment Verification was outlined in the whitepaper.

The protocol is meant to be used between peers, not between users and nodes.

To have some data : https://www.google.com/intl/en/ipv6/statistics.html While progress is slow, it is constant and we're reaching 40% of IPv6 availability in 2022, from pretty much 0% in 2010. I'm confident we'll get there.

I always find it amusing that IPv6 usage peaks on weekends. Seems home and mobile users have better IPv6 connectivity than corporate users.

Anyone running v6 only and bridging to v4 on the edge?

> Anyone running v6 only and bridging to v4 on the edge?

If you are on T-Mobile USA you are IPv6-only on your mobile device:

* https://www.youtube.com/watch?v=nNMNglk_CvE

Lots of folks are probably IPv6-only without realizing it.

It seems that this article is missing the forest for the trees. The biggest improvement will come not from the raw speed but from the entire IPv6 eco-system. For example, the new segment routing for IPv6 or SRv6 should improve the Quality of Service (QoS) for examples bandwidth, delay and jitter by having control at the edge. This is unlike MPLS where the control is done in the core itself and that's why MPLS is call…

A poor link - a book written by Huwaei doesn't scream "This is a widely used standard" Wikipedia would be a far better link, as it has links to RFCs, Cisco, Juniper Arista etc pages on it, and generally lets normal people who likely haven't heard of it read about it

Sheesh, it take real guts to dismiss a book written by engineers who themselves directly involved in coming up with open industry networking standards, and currently working with arguably the biggest networking and communication company in the world. This take the idiom of "judge a book by its cover" to a whole new level.

SRv6 is not going to transform the quality of experience/quality of service that you see from Internet applications. Traffic engineering technologies like this (MPLS-based, IP-based, emulated circuit based...) are used inside networks to select paths through them, this has been done for many years, and the segment routing data-plane - whether it be MPLS or IPv6, is a different realisation of how to achieve that path…

Yes sure MPLS works as combustion engines work as long we can remember, but it's not stopping EV as a new contender as the near future vehicle platform whether we like it or not. Now we have hybrid MPLS or SR-MPLS as a stopgap measure similar to what we have now with PHEV, etc. Personally I think the networking industry has already learned their mistakes from the ATM days and hopefully SRv6 will take off for better and more effective IP based networking.

This test is pretty flawed:

> IPv4 requests went first, then IPv6, and we recorded the average latency of the 3 requests as the resulting data point (using a float value in milliseconds).

On wifi, the IPv4 requests are going to wake up your radio, and then the latency is going to be better for the IPv6.

On wired, there's very little difference, since there's no radio wakeup delay.

Pinging your default gateway isn't much of a test anyway.

You're talking about displacing an incumbent, not competing technologies. IPv6 will win, once people stop sitting on their hands. Companies now are being effectively forced to adopt it due to exhaustion of the range.. CGNAT is bigger than ever and is causing real issues so most phones are dual homed with IPv6 behind a v4 CGNAT. Like climate change, its a "future problem" until its practically staring you in the face,…

All cheap stuff will support IPv6 due to China mandating full IPv6 support. I suspect China will eventually drag the kicking and screaming west to IPv6-land.

I don't understand what this means. This was not a defence of MPLS, but rather an observation that says that the fundamental domains and business logic around externally-selected TE paths do not change because we change what header instructs the network to steer packets. It's still not going to make sense to have external users try and use the "premium" paths in the network without some recompense to keep scaling them, equally, there needs to be some incentive for users to choose a "less than best" path.

Quite honestly -- this kind of marketing hype and hyperbole is what is wrong with the whole area of SR today (and I say this as someone that was _very_ involved). We've completely lost the ability to say what it is we're solving, and why we're doing it. We're driving disparate architectures into silicon where there's opportunity cost for the functionality. We're having political disagreements within the IETF based on folks trying to keep political control of technologies, not worrying about the efficacy for the industry. It's all pretty broken. YMMV.
