Firstly, what is Azure VIP (Virtual IP address) and DIP (internal IP address assigned by Azure DHCP) on Microsoft Azure?
Microsoft Azure VM has two known IP addresses:
- VIP: Public IP address pointing to Azure Cloud Service where VM is deployed. Every Cloud Service has a VIP and every Cloud Service can have several VMs. A VIP assigned to Cloud Service won’t be released until last VM on that Cloud Service is Stopped (De-allocated)
- DIP: Internal IP address assigned to the VM by Azure DHCP.
