# Create and manage networks
|
|
|
|
<div className="text">The OpenStack Networking service provides a scalable system for managing the network connectivity within an OpenStack cloud deployment. It can easily and quickly react to changing network needs (for example, creating and assigning new IP addresses).<br/><br/>Networking in OpenStack is complex. This section provides the basic instructions for creating a network and a router. For detailed information about managing networks, refer to the <span style={{textDecoration:'underline', color:'blue'}}>OpenStack Networking Guide.</span></div> <br/>
