             Summary: Implement DNS-based PING
                 Key: JGRP-2139
                 URL: https://issues.jboss.org/browse/JGRP-2139
             Project: JGroups
          Issue Type: Enhancement
         Environment: * OpenShift and Kubernetes (service discovery is done using SRV records)
* Any other environment that use {{A}} or {{SRV}} DNS records
            Reporter: Sebastian Łaskawiec
            Assignee: Sebastian Łaskawiec


DNS Discovery might be very useful in Cloud environments (such as Kubernetes or OpenShift). They expose Services (which act as Load Balancers and Clustered Virtual IPs for Pods (Docker Containers)) with DNS {{SRV}} entries using the following scheme: {{_port._proto.ENDPOINT.service.namespace.sv.cluster.local}} (see [this issue|https://github.com/kubernetes/kubernetes/issues/29420] for more information). 

The implementation should also allow the following:
* Change the DNS Server address
* Change or override TTL values
* Change DNS record type (either {{A}} or {{SRV}}
** If the record type is {{SRV}}, it should also allow parting port
