Technical Terms


An Application Programming Interface (API) is a source code-based specification intended to be used as an interface by software components to communicate with each other. An API may include specifications for routines, data structures, object classes, and variables.

PhoenixNAP has created an API that allows you to interface with our Cloud to perform many actions available in the Cloud Admin. You can view the parameters of the API in the Cloud API Guide.

MAC Spoofing

MAC Spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device.

The changing of the assigned MAC address may allow the bypassing of Access Control Lists on servers or routers, either hiding a computer on a network or allowing it to impersonate another network device.

A user may wish to legitimately spoof the MAC address of a previous hardware device in order to reacquire connectivity after hardware failure.


A Virtual Private Cloud (VPC) is a private cloud existing within a shared or public cloud (i.e. the Intercloud).

Public Cloud is a form of VPC, which allows its cloud service to be connected to legacy infrastructure over an IPsec virtual private network (VPN) connection.
