# NP Net TCP/IP Overview

NP Net TCP/IP connects the servers together using Ethernet. NP Net TCP/IP can use an existing private network, or it can send messages over a public network. The high bandwidth of Ethernet connections allows for a large volume of network traffic, providing users with network service that is almost indistinguishable from local messaging.

In order to use NP Net TCP/IP, a server also must have the Unified TCP/IP Interface optional feature installed. This optional feature provides a single point of configuration for all TCP/IP applications on these servers.
