# Cogent: products, competitors, and capabilities in Dedicated internet access

> Cogent’s DIA offer is specific about port, routing, and published network guarantees. A buyer still needs to establish whether a site is on-net or needs a local loop, because availability and installation differ. This public-research preview is not demand-ranked or a vendor recommendation.
