They seem to be IPv6 host addresses that it uses. I do not have that.
When I try to resolve from command line with host they resolves.
Does this mean something to someone?

if it does, then resolve it in /etc/gai.conf
and then remove -4 for bind

i think you found a hostname nameserver that have non working ipv4 ?,
and ipv6 is failing on ips
remember ipv4 nameservers can resolve ipv6 and vise versa
find nameserver for this domains, check the nameserver ip can ping or
listen to port 53, both on ipv4 and ipv6
if it works on ipv4 then you can force your own dns resolver to use ipv4
for this host only in /etc/gai.conf
possible check that you prefer ipv6 first :)
default is ipv4 first
ping6 -c 3 ipv6.google.com
ping -c 3 ipv4.google.com
just to rule out you have working ipv6 aswell
