nslookup worked as excepted:

k exec -it deployments/dnsutils -- nslookup sleep.default.svc.cluster.local
Server:		fd00:10:96::a
Address:	fd00:10:96::a#53

Name:	sleep.default.svc.cluster.local
Address: fd00:10:96::1d41

k exec -it deployments/dnsutils -- cat /etc/resolv.conf
search default.svc.cluster.local svc.cluster.local cluster.local
nameserver fd00:10:96::a
options ndots:5
