It may be trival, but head to icaan accredited registrar list and you have more than 2800 competitors to transfer your domain to.

Pick one that supports glue records, ipv6 glue, and dnssec, but unfortunately the icaan list does not provide this information...

The one I use for 20+ years is gkg.net. they support all of the above, and "hosts" (glue records) supports ipv4 and ipv6, but also multiple addresses per name.

Gkg IANA number is 93 so they are here for a long time.
