vRealize Infrastructure Navigator discovers and displays machines, services, and dependencies that are external to the current vCenter Server. If an external machine has more than one IP address, each address is discovered as a separate external machine. If multiple external machines have the same IP address, they are discovered as a single external machine.

An external virtual machine appears in a gray color in the dependency map and is represented by its DNS name. If a DNS name does not exist, the dependency map displays the IP address of the external virtual machine.

If you select a machine that is external to your current vCenter Server environment, the information panel displays the details of the selected machine below the dependency table and dependency map.

The Service tab displays the services running on the external virtual machine. The General tab displays the message

This is an external IP address. It can be either a physical machine or a virtual machine, which is not managed by the vCenter Server that Navigator is deployed on.
