DNS

OpenShift Network Playground DNS

For the host, it uses the NetworkManager + dnsmasq combination. The required entries are added in the /etc/hosts and /etc/NetworkManger/dnsmasq.d/openshift-network-playground.conf files.

INFO

For host DNS issues, restart NetworkManger

Single Node OpenShift DNS

Since the SNO can be deplyed as single-stack IPv6 cluster in the ONP environment, the DNS64 and NAT64 plays the key role to enable the outside connectivity for the nodes. The DNS64 uses the bind package.
