I have successfully added the secondary DHCP private IP address in azure portal. when I tried to run ipconfig /all, it shows only one IP address and that is primary IP address. Then I tried to add the IP address from inside windows operating system in "Advanced TCP/IP settings" it is not allowing. The "Add" button is greyed out. I am assuming that this is happening due to "DHCP enabled" hence I am unable to add another secondary DHCP private IP address.

Please guide me how to proceed further configuring secondary DHCP private IP address from inside windows operating system.

    Hello,

    When using DHCP, you cannot manually add multiple IP addresses to a single network interface from within the Windows operating system. DHCP automatically assigns IP addresses to the NIC, and you won't be able to add additional IP addresses manually.

    Can I deploy a DHCP server in a VNet?

    Azure VNets provide DHCP service and DNS to VMs and client/server DHCP (source port UDP/68, destination port UDP/67) not supported in a VNet. You cannot deploy your own DHCP service to receive and provide unicast/broadcast client/server DHCP traffic for endpoints inside a VNet. It is also an unsupported scenario to deploy a DHCP server VM with the intent to receive unicast DHCP relay (source port UDP/67, destination port UDP/67) DHCP traffic.
