This is not the same. #43 We all use datacenter Spring Eureka Server.

The 192.168.1.5:datastash:9999 is service DATASTASH instance id. if don't have this property, it will use hostName as the instance id. Instance id will conflict when multiple services are deployed on a single server.

But #43 has an issues, start heartbeat will have a 404 error, because it's not in use instance id as the only sign of service. Considering that it has been a long time, I resubmitted a PR.
