If that anecdote is true, they're doing something wrong. What I hear is there is no performance impact in general, with some reports of bulk data moving faster with IPv6 (probably due to some kind of MTU issue). Regards Brian Carpenter On 14-Jul-22 09:16, Juha Saarinen wrote:

As a small ISP, my question is, what benefit do I get by adding IPv6? I have enough IPv4 addresses for all my clients and although I get the occasional client asking when we'll make IPv6 available, when I ask them why they want it, the answer is mostly something that sounds like "because IPv6" Stan Rivett ------------------ Netspeed PO Box 5691 Dunedin P: +64 3 481 7245 C: +64 21 323 841 ------------------ On Thu, 14 Jul 2022 at 09:47, Brian E Carpenter wrote:

IPv6 is largely not about the client. Its about what is good for the co-operative network we call The Internet.

The other benefit is having the network ready and operational for when it does become strictly required.

It’s not all in one direction - Do you provide hosting services and if so then do those people who host with you want to maximise the reach of whatever it is they are hosting?

If they have good reason to handle IPv6 clients at scale, they can always use Cloudflare while remaining on IPv4 in-house. I don't know if Cloudflare publish stats. Brian

That used to be true, due to a lack of ASIC/FPGA acceleration for IPv6 packets, forcing them to go through the control plane. I would hope that most, if not all vendors now do hardware switching for IPv6 on anything build in the last 10 years. On Thu, 14 Jul 2022 at 09:16, Juha Saarinen wrote:

Good point Tracy B , however the CPEs are mostly managed by TR-069 and IPv6 can be enabled remotely Regards Ahmad Saeed From: Tracy Briscoe [mailto:tracyb(a)coppertop.net.nz] On Behalf Of nznog(a)coppertop.net.nz Sent: Thursday, 14 July 2022 8:43 PM To: 'Matt Brown' Cc: nznog(a)list.waikato.ac.nz Subject: [nznog] Re: IPv6 status? I wonder how much of the growth in IPv6 traffic is limited by the ISP supplied router not having it enabled, rather than the network not supporting it. That was the problem for me – put a tick in the right box and IPv6 started working. Not many home users are going to look for said check box, especially when it is buried 3 clicks deep under the advanced settings.
