Managed routers are a great way to save money, increase productivity, and reduce downtime, and they’re so effective that most large companies also use them. A managed router's benefits are, it uses one or more physical interfaces (or ports) to connect to the outside world. Each port has its unique IP address, which the service provider typically assigns. Each time you add another interface to your managed router, you must assign a new IP address that helps to enhance the benefits of using Managed Router Services.
