Question 100 - NCP-MCI-6.5 discussion

When a VM is connected to a Nutanix managed network, the IP address is assigned when the VM is powered on. A Nutanix managed network is a network that is created and managed by Prism Central using IP address management (IPAM). IPAM allows Prism Central to automatically assign IP addresses to VMs from a pool of available addresses in a subnet.IPAM also tracks the IP address usage and availability across clusters and networks4.

When a VM is connected to a Nutanix managed network, the administrator can choose one of the following assignment types for the IP address:

Assign Static IP: This option allows the administrator to manually specify a static IP address for the VM from the subnet range. The IP address will not change unless the administrator changes it.

Assign with DHCP: This option allows Prism Central to dynamically assign an IP address for the VM from the subnet range using DHCP. The IP address may change depending on the DHCP lease time and availability.

No Private IP: This option allows the administrator to skip assigning an IP address for the VM.This option is useful for scenarios where the administrator wants to use an external IPAM solution or assign an IP address later5.

Regardless of the assignment type, the IP address is assigned when the VM is powered on. This is because Prism Central needs to communicate with the hypervisor (AHV or ESXi) to configure the virtual NIC (vNIC) of the VM with the IP address information.This communication can only happen when the VM is in a powered on state6.
