public class DnsClusterResolver
extends java.lang.Object
implements ClusterResolver<EurekaEndpoint>

Resolves cluster addresses from DNS. If the provided name contains only CNAME entry, the cluster server pool contains effectively single item, that may however resolve to different IPs. This is not recommended configuration. In the configuration where DNS name points to A record, all IPs from that record are loaded. This resolver is not zone aware.
