The map shows where DCI cable internet is available and DCI speeds in different areas. When different max speeds are available at different addresses within a hex, color is determined by the fastest speed.
Colored hexagons indicate where DCI services at least one address. Internet service is not necessarily available at every location within a colored hex.
Select a city to show DCI Cable availability in the surrounding area.
Zoom out to view DCI Cable availability and speeds at the national level. However, the map works best when zoomed in, exploring DCI Cable availability in specific regions.
The availability or speed of service at a single address can dictate the color of the hexagon the address falls within. Accordingly, national-scale views with large hexagons will smooth over local variations in internet availability and speeds.
Broadband Map's information on DCI cable availability relies heavily on the June 2026 data from the FCC's Broadband Data Collection program (published October 2026).
