[ipv6-wg] web services to ipv6

Hello everyone on the list! this is my first post, sorry if this is not the right place for my question.
I currently reside in Spain, which most ISPs do not assign ipv6 to end users and with a penetration of 3% *1 I think that percentage has not changed much since 2021, it only remains to say, incredible!
Previously I have used Hurricane Electric *2 when I lived in Bolivia, South America only to browse ipv6 sites.
I have seen the website august.tw  *3
"This is a non-profit project for learning, education and research.Our goal is to support the ever-growing internet community that wants to experiment and gain hands-on experience with the real world BGP. We provide the following services.
"
I am interested for personal use.

-Free IPv4/IPv6 BGP tunnel-Public NAT64 server available at 2602:fc23:18::7-Public Teredo server available at teredo.august.tw
Is this website known by the community?Or have any of the community users used these services?These services can be recommended for personal use?
Data, I was struck by the logo shown at the bottom with a link to RIPE NCC and ARIN.
I appreciate any help in this regard, thank you very much, best regards!
