500+ providers.
One search.

BIA checks 500+ providers at your address, including national carriers like AT&T, Verizon, Comcast, and Lumen, plus regional fiber providers like FirstLight, Everstream, and Segra. We compare Tier 1 national backbone carriers, Tier 2 regional fiber and cable providers, and dedicated internet access (DIA) options.

Tier 1 providers own global backbone infrastructure and peer directly with other Tier 1 networks at no cost — examples include AT&T, Verizon, Lumen, Cogent, and Zayo. Tier 2 providers own their own infrastructure in specific regions and purchase transit from Tier 1 carriers for traffic outside their footprint. For most businesses, Tier 2 regional providers offer equivalent reliability and often better pricing than national carriers in their coverage area.

Dedicated Internet Access (DIA) is a business-grade fiber connection where your bandwidth is not shared with other customers. Unlike cable or consumer-grade fiber, DIA provides symmetrical upload and download speeds, a guaranteed SLA (Service Level Agreement) with uptime commitments typically at 99.99%, and a static IP address. DIA is recommended for businesses that rely on VoIP, video conferencing, cloud applications, or need consistent upload speeds.

Yes. Spectrum and Comcast Business are both in our network. For most addresses in their coverage areas, we can provide same-day quotes without requiring a formal availability check. Both offer cable-based business internet and, in select markets, fiber options. We compare their pricing alongside fiber-only providers so you can see the full picture.

We use a three-source verification system: (1) carrier-uploaded building lists that tell us exactly which buildings have fiber already installed (On Net) or within short extension range (Near Net); (2) FCC Broadband Data Collection records matched to your Census block; and (3) our proprietary H3 hex coverage database covering 500+ providers nationally. This layered approach gives us higher accuracy than any single data source.

Yes. We don't quote Tier 3 providers for primary business internet connections. Tier 3 providers lease capacity from Tier 1 and 2 carriers rather than owning their own infrastructure, which creates latency risk and limits their ability to resolve outages quickly. We will note when a Tier 3 provider is the only option in an area and explain the tradeoffs — but we won't recommend them as a primary connection for business-critical operations.
