Does the Azure internal load balancer have a hidden hostname? I know the public one does but I thought the internal one also had one with a *.internal.cloudapp.net suffix at some point, similar to virtual machines:
[azureuser@bastion ~]$ hostname -f
bastion.jelt1kdogtheznzc1giioh4lrd.phx.internal.cloudapp.net
No, it does not, you can use hostfiles and\or dns entries in your own dns servers to assign hostnames to internal load balancer
