 The *traffic* plugins uses the name(s) specified in the Server Block to create fully qualified

 For SRV queries all endpoints are returned, the SRV target names are synthesized:
 `endpoint-<N>.web.lb.example.org` to take the example from above. *N* is an integer starting with 0.
 
-The gRPC load balancer name: `_grpclb._tcp.<cluster>.<zone>` will also be resolved in the same way
