2,135 ISPs covered

Brand, holding company, technology code (fiber / cable / copper / fixed-wireless / satellite), max download, max upload, low-latency flag, residential/business split.

Sub-second lookups

Address resolution flows through property_sales fuzzy match → block geoid → BDC range scan → JSON. Falls back to tract centroid if the block isn't matched.
