Choosing the right internet connectivity option is a key step for any business that relies on network performance — whether for cloud services, remote work, data centers, or online platforms. Two common connectivity models are IP Transit and Dedicated Internet Access (DIA). While both provide internet access, they serve different purposes. This article explains the differences in a practical, easy-to-understand way so you can make an informed decision. What Is IP Transit? IP Transit is a service that connects your network to the global internet routing system using BGP (Border Gateway Protocol). It is typically used by: With IP Transit, your network becomes part of the broader internet infrastructure, allowing flexible routing and access to global peers. For more detail, see DCConnect’s IP Transit page What Is Dedicated Internet Access (DIA)? Dedicated Internet Access (DIA) provides a fixed, uncontended internet connection with guaranteed bandwidth between your business and your provider’s network. DIA is designed for organizations that require: This model focuses on delivering consistent internet experience for office productivity, cloud applications, and data traffic.
