If your domain's authoritative name servers have only IPv6
addresses, then your domain will not be resolvable by many resolvers
on the Internet, because many of them only have IPv4 connectivity.
This was in 2014 but I'm not sure it changed a lot since:

I just re-ran a similar test and got about a 71% success rate:
https://atlas.ripe.net/measurements/23732712/
While technically slightly better than 67% success rate measured 5 years
ago, to me this means that running an IPv6-only name server it is
basically not possible.
I also ran a version using IPv6-enabled probes, and got an 89% success rate:
https://atlas.ripe.net/measurements/23734035
I think that even 90% is still not good enough to allow you to run an
IPv6-only name server, at least for general Internet usage. 😞
