IPv6 for small networks

[jbo@]

I'd like to collect some opinions and experiences about IPv6 for small networks (mainly home networks and SME).

So far, I have never bothered setting up IPv6. Mostly because back in the days when IPv6 first became a discussion for your hobby sysadmin there were some discussions about potential security issues in the protocol. I never bothered looking into the extend or truth of that nor whether any potential issues have been addressed/resolved in the meantime.
Furthermore, back in the day there were very few networks/servers that would actually talk IPv6 to you.

As per my understanding, one of the main benefits of going IPv6 would be to eliminate the need for NAT. Is my understanding here correct?
Are there any other notable benefits for small networks (with publicly reachable servers)?

Are you guys running IPv6 setups? If so, why? If not, why?
For those of you who are running IPv6 setups, are you running exclusively IPv6 or are you running both IPv4 and IPv6?

Internet speed increased if website is reachable with iPV6. in my case 50%+ ( im using sim card for internet 4G ) but i did it on my router .. i choose ipv4v6 option and when i installed FreeBSD installer outo configured ipv6 and i used cloudflare dns for ipv6 and ipv4 ( obvioulsy dns is optional )
I dont use ssh with ipv6... and in my understanding if ipv6 is enabled and website is reachable trough ipv6 - i connect trough it.
Also i never added static ipv6 like i did with ipv4.
with ipv6 im able to get up to 180Mbps when only ipv4 i barely reached 80. Also i do have sim card restraints when people using internet etc. but while im typing this post im downloading packages with pip, using speed test and i have 103.4Mbps download and 47.95 upload.
Also speedtest.com is a bit bias if i remember ... people used not to recomend me this so in fast.com i have 97 download and 45 upload. These speed where not achievable with ipv4 only.
And only ipv6 makes no sense yet due to not every website is reachable.
But maybe im wrong ?

Homelab with dual-stack and with DHCP option 108 enabled. My Win laptop is IPv6-only where the legacy stack is disabled. I also run a local DNS64 + NAT64 so I can access websites that are still using legacy-IP. Phones are IPv6-mostly(Android/Apple). No problems so far on a daily use.

For the speed part, if you are on CGNAT + IPv6, find a dual-stack website, and during peak hours access that site over CGNAT and then access that same site over IPv6 again.

IPv6 is end-to-end communication access, how the net was intended to be. Major sites are already on IPv6 for awhile now.

IPv6 is the gold citizen over legacy IP.

This site is on IPv6 so kudos to them for enabling it, unlike other sites where people discuss about IPv6 yet the site itself isn't IPv6 enabled.

fwiw, at home I run Google's wifi routers on ipv6 for my wife's notebook and our TV for many years. I'm wired in. Always worked but I really haven't looked at any statistics on it in a long time.
