+          Can I include On-premises IPs in the backend pool of Azure Load Balancer?
+        answer: |
+          No, Azure Load Balancer does not support the direct addition of On-premises IPs to its backend pool. The load balancer employs a platform-specific IP address (168.63.129.16) for health probes, limited to communication within Azure's virtual network. Consequently, it cannot probe resources located on-premises.
