# Why Doesn't NetBox Scan for IPs?
NetBox does not do any probing of IP addresses natively, for several reasons.

In this scenario, there are five **physical** circuits: One to each of the five sites from the provider. These five circuits carry traffic to support an overlay comprising four **virtual circuits** (one to each spoke site from the hub). A physical circuit is responsible for the physical transmission of a signal from one point to another, whereas a virtual circuit is a purely logical construct.
NetBox models only physical circuits, which can be terminated to physical interfaces on devices. While the ability to model virtual circuits would certainly be useful, it is impractical to account for the myriad technologies which might be used to establish a topology.

# How Can I Add New Interface Form Factors?
The set of available interface form factors is statically defined in NetBox; users cannot add arbitrary form factors. This is done to remove the potential for creating duplicate or illegitimate form factors that would degrade the data model. If there's a form factor you'd like to see added to NetBox, consider opening a [feature request](https://github.com/digitalocean/netbox/issues) detailing your use case. (However, bear in mind that only actual hardware interface types will be added.)
