I have considered many times on being "ready" for IPv6. The problem is, there is currently no demand and everything works perfectly fine with IPv4. My ISP provides IPv6 and i have tried it in the past on the Mikrotik router and it seemed to work just fine. I did get a WAN IPv6 from my provider on the pfSense but i switched it off because i had no need.
 
Don't forget that IPv6 is NAT-less and lighter for the router to handle.

NAT and IPv4 routing are hardware accelerated and very little impact on the router. I doubt that the IPv6 hardware routing/firewall acceleration is as robust and streamlined at this point. At worst, it is the same.

Do some pings and speedtests with both, show the benefit of IPv6, I haven't seen it. In many cases I've seen it perform worse.
 
No pinging, no speed testing needed. Just use your network as normal.

IPv6 is noticibly faster than IPv4.

Something is wrong with your IPv4 stack then.

Yes it is. Results may vary depending on location, ISP, destination and service. But without comparative testing any differences could well be placebo or confirmation bias. How many times have we seen people swear that their Wi-Fi has got better or worse after a firmware update when there was no actual change to the Wi-Fi. No testing, no proof.
 
I am 59 years old i am using pfSense as router & firewall.

IPv6 is faster, more secure, and is the future.
Google and read about the differences and you know.

Long lonngggg time I thought: IPV6? No way, never, to complicated, not in the mood to learn or to change, why should i, right?

Then a younger friend motivated me to just start with IPv6. He assured me it is not complicated it just looks complicated.
Then I did start with it to learn and to implement it in my pfSense and my 8 subnets (vlans).

Bit by bit I made IPv6 work in all my subnets and works very well.
I still don't know everything yet but everyday i little bit more.

My network is now dual stack for almost a year and I'm definitely not going back.

30% of the internet already runs on IPv6 and in the future it will be more and more till eventually everything will be IPv6.

Besides all the above it is just fun the learn this while i was thinking of it for years and i didn't want to.
Now I know enough to make my network work on IPv4 ánd IPv6 i am happy i did it.

It is not as complicated as you think it is.

In my DMZ i have all kinds of servers running on my Proxmox system everything is IPv6 my websites are IPv6 it is fun to do it step by step evolve to learn more and more.

Please show evidence or any facts that show it is faster or more secure.

It has the potential to be both. Unfortunately that potential won't be realized for a very long time, if ever. They're potentially about to release another 268 million IPv4 IPs.
 
I am not going to give you evidence because i am not in the mood and i don't care.
I use IPv6 everyday that is my prove. I notice the difference every day.
If you don't want to learn or use IPv6 then oke by me 👍
For those that are willing just do it, just start learning it is fun.

I learned it over a decade ago, have implemented and used it personally and professionally. But go ahead and have your fun, just don't post bogus info and mislead people into potentially taking on unnecessary risk on their inexpensive home wifi router for no benefit.

Unless you are switching back and forth between v4 and v6 every day, you aren't noticing any difference. Feel free to enjoy the pseudo effect, why bother with silly evidence and facts.
 
How do you guys know you’re actually using IPv6 (and not IPv4) when you say you notice a difference?

I test it by switching IPv4/6 on and off in my interface settings.
Specially in the beginning last year i was curious if i would notice speed difference.
Not that it was that important.
The most fun was in the learning and the step by step going forward and thank god it was not that difficult as i always thought.

Ha, no wonder you think 6 is faster. If you simply disable 6 on an interface thinking you're now using 4, your clients don't know it, and continue to try to use 6 (6 is higher priority), eventually retrying and using 4. So yeah, that will definitely perform terribly.

I know you're new but fair warning, there are many here that can smell BS a mile away.

Voila!

Oh i believe you know very well how it smells.
 

Based on ping and jitter you're hitting two totally different servers, the IPv4 one is much further away, and latency impacts throughput. Or you've got your IPv4 totally misconfigured.

Do lots of speed tests to several different servers. Or better yet test with two PCs and iperf.
 
You will never be satisfied whatever i do so no not in the mood.
I mean well to the people who want to learn not in the mood to bicker back and forth.
