Which IPv6 to set for my nameservers? ("No AAAA records for any NS")

    Hello,
    my domain.com is using nameservers of my otherdomain.com
    ns1.otherdomain.com
    ns2.otherdomain.com
    SEMrush
    and https://ip6.nl/#domain.com complained that:

    DNS servers IPv6: No AAAA records for any NS
    IPv6-only DNS: Doesn't work

    after i have setup new ns1 and ns2 AAAA records to the possibly Cloudflare dns IPv6:
    2606:4700:4700::1001
    2606:4700:4700::1111

    It started showing these on ip6.nl yet it still says IPv6-only DNS does not work. domain.com hosting server provider says they does not have IPv6 for their server hostname. Though they assigned IPv6 to my site.

    Question: which DNS IPv6 should i set for my NSs? I assume the IP my hosting provider assigned to my site (for example x:x:x:x:x:x:0:30 not as it is not a gateway)? Is it good idea to leave it to mentioned IPv6 or should i rather remove these "DNS IPv6" records?

    When i do Linux command:
    $ host -6 domain.com ns1.otherdomain.com

    it shows that it is using the Cloudflare IPv6 above mentioned and shows IPv4+6 assigned to my hosting account. So that seems OK - resolving. Yet my questions and ip6.nl error "IPv6-only DNS: Doesn't work" remains.

    I am using rather exotic TLD .xyz and it is not listed among "Top Level Domains supporting IPv6 Glue" https://www.sixxs.net/faq/dns/?faq=ipv6glue unsure how big problem it is for the v6 connectivity.
