Are you using IPv6? - What about Domino?

IPv4 addresses are becoming a rare resource for years. But still the adoption of the next generation IPv6 protocol (which is available for ages) isn't great.
Most operating systems, routers and other infrastructure components are IPv6 ready for years.
I looked into Domino IPv6 support quite a while ago and some of my servers are dual homed. But mostly with separate DNS names mainly for testing.
There is still only one customer I know about making the switching for their Domino servers.
I looked into all the different aspects including logging in domlog.nsf and even SMTP Extension Managers a while ago and it just works the same way.
The basic setting you need to set is: notes.ini TCP_EnableIPv6=1
Domino IPv6 documentation
There are some other more specific settings available to configure IPv6 addresses in different places of Domino.
In some places IPv6 addresses need to specified with square brackets.

How far is IPv6 enablement completed?
One statistic (https://pulse.internetsociety.org/technologies) says that only around 50% of 1000 websites support IPv6 beginning of 2024.
Also Google's statistics should a similar adoption rate in more general: https://www.google.com/intl/en/ipv6/statistics.html
Additional resources
The Internet Society website has an interesting IPv6 section with more details.

How are you using IPv6 today?
Some providers increased their prices for IPv4 addressed. And for some test servers I might switch completely to IPv6.
I would be interested to hear from you, how much you adopted IPv6 on client and server side.
Did you face any specific challenges when trying to make the move?
Specially for Domino and related products.
