To become an Internet Service Provider, you form a business entity, build or lease the physical network, obtain an Autonomous System Number and IP address blocks from ARIN, arrange upstream bandwidth, register with the FCC and file the required revenue and coverage reports, comply with CALEA and DMCA obligations, secure pole attachments and rights-of-way, and register with your state before turning up service. Capital ranges from roughly $50,000 to $200,000 for a small fixed wireless build to several million dollars for fiber to the home, and the regulatory calendar starts the week you begin offering service.
Form the Business and Size the Capital
Start with an LLC or corporation. Owning telecommunications infrastructure carries liability that you do not want touching personal assets, and commercial landlords, equipment vendors, and upstream carriers will ask for proof of insurance before they sign anything. You will also need an EIN from the IRS, a business bank account, and general liability coverage at a minimum.
Capital requirements track your delivery method. A fixed wireless operation serving a rural community can launch on $50,000 to $200,000 in equipment, tower leases, and licensing. A fiber-to-the-home build in a suburban market can easily reach the millions once trenching or aerial construction, permits, core network equipment, and pre-launch operating expenses are counted. Budget for three to six months of operating costs before revenue arrives. Subscriber growth is always slower than projections suggest.
Write a real business plan. Upstream bandwidth providers, lenders, and ARIN will expect a network topology map, a coverage plan, and financial projections. The exercise of pricing the specific hardware, transit, and labor exposes gaps while they are still cheap to fix.
Build the Network
Your core is a set of routers that can run the Border Gateway Protocol, the routing system that lets your network exchange traffic with the rest of the internet. These are not consumer devices. They need high packet-per-second capacity for thousands of simultaneous sessions and modern encapsulation support so traffic types do not degrade against each other.
High-capacity switches sit between the core routers and subscriber connections. Choose 10 Gbps or faster ports to leave room for growth. Bottlenecks at this layer are the most common source of peak-hour complaints, and replacing underpowered switches after launch is disruptive and expensive.
The last mile depends on your delivery choice. Fiber has the highest bandwidth ceiling and the longest useful life, but per-mile construction costs are significant. Fixed wireless using licensed or unlicensed spectrum deploys faster and cheaper where trenching is impractical, at the cost of some bandwidth and weather resilience. Each medium needs its own interface cards and transceivers to maintain signal integrity.
All of it lives in a secured facility, often called a Point of Presence, with redundant power, cooling, and physical security. If you are not building your own, you will lease rack space in a colocation site. Organized cabling is not cosmetic. Tangled cable restricts airflow and turns a 2 a.m. failure into a much longer outage.
Get Your Internet Number Resources
Autonomous System Number
To appear as an independent network on the global internet, you need an Autonomous System Number from the American Registry for Internet Numbers. You qualify by naming two upstream providers you will multihome through, or by describing a routing policy that differs from your neighbors. ARIN no longer requires copies of contracts or invoices.1American Registry for Internet Numbers. How to Request an ASN from ARIN
IPv4 and IPv6 Blocks
Every device on your network needs an IP address. IPv6 blocks are readily available through ARIN and should anchor your long-term addressing plan. IPv4 is different. The global free pool is nearly exhausted, with only a few million addresses left across all regional registries, so most new ISPs buy IPv4 space on the secondary transfer market. As of early 2026, the mean transfer price is roughly $22 per address, down significantly from peaks above $50 in prior years.2American Registry for Internet Numbers. IP Addresses Through 2025
Upstream Transit and Peering
Numbers make you visible; transit carries the traffic. You pay upstream carriers a per-megabit rate to accept your traffic and deliver it to destinations you cannot reach directly. In competitive U.S. markets, 10 Gigabit Ethernet transit runs around $0.07 per Mbps per month, and 100 Gigabit ports can drop to $0.05 per Mbps, with variation by city and commitment. Local access and installation are billed separately.
Peering lets you exchange traffic directly with another network without paying transit on it, giving your subscribers a shorter path to that network’s content. Multihoming across at least two upstream providers is both an ARIN qualification path and a baseline resilience measure. If one link fails, subscribers stay online on the other.
File With the FCC
CORES Registration and Form 499
Every entity doing business with the FCC registers through the Commission Registration System and receives a 10-digit FCC Registration Number. New telecommunications service providers must file FCC Form 499-A within one week of offering service to the public, and existing providers file annually on the prior year’s revenue.3Federal Communications Commission. Common Carrier Filing Requirements This filing determines your contributions to the Universal Service Fund, which subsidizes broadband in underserved areas, schools, libraries, and rural health care facilities.
USF is not a rounding error. The contribution factor for the first quarter of 2026 is 37.6 percent of interstate and international telecommunications revenues.4Federal Communications Commission. USF Contribution Factor 1Q2026 If your annual USF contribution would exceed $10,000, you also file FCC Form 499-Q each quarter.3Federal Communications Commission. Common Carrier Filing Requirements Missed filings can bring fines or revocation of operating authority, so put these deadlines on the compliance calendar from day one.
Broadband Data Collection
Twice a year, you report where you offer service, at what speeds, and using what technology through the FCC’s Broadband Data Collection system. Data as of December 31 is due the following March 1, and data as of June 30 is due the following September 1.5Broadband Data Collection Help Center. Broadband Data Collection (BDC) FAQs The old Form 477 broadband deployment filing is gone; availability data goes through BDC, and voice and broadband subscription data still flow through the same portal.6Federal Communications Commission. Broadband Data Task Force Announces Opening of Eighth Broadband Data Collection Filing Window
Coverage can be submitted as polygon shapefiles or as a CSV listing each serviceable location with its Fabric location ID, technology type, and maximum advertised speeds.5Broadband Data Collection Help Center. Broadband Data Collection (BDC) FAQs You must report every location where you can deliver service within 10 business days at a standard installation charge, and the FCC cross-references your filings against consumer challenges.6Federal Communications Commission. Broadband Data Task Force Announces Opening of Eighth Broadband Data Collection Filing Window
Broadband Consumer Labels
Every standalone broadband plan needs a consumer label at the point of sale, online and in any physical storefront. The label resembles a nutrition facts panel and must disclose monthly price, introductory rate terms, data allowances, typical download and upload speeds, and links to your network management and privacy policies.7Federal Communications Commission. Broadband Consumer Labels Display it in close proximity to any plan advertisement, not behind a link or icon.
You must also publish the same information in a machine-readable CSV file hosted at a dedicated URL on your website, and reference that URL in your transparency disclosures.8Federal Communications Commission. Specifications for the Broadband Consumer Label – Machine-Readable Data Files The label and machine-readable obligations apply to all providers regardless of size.
CALEA and DMCA Obligations
The Communications Assistance for Law Enforcement Act requires telecommunications carriers to design their networks so law enforcement can execute authorized electronic surveillance. In 2005, the FCC extended CALEA to facilities-based broadband internet access providers and interconnected VoIP providers, which means the obligation applies even if you only sell internet service. You must be able to isolate and deliver a specific subscriber’s traffic on a lawful court order, designate a point of contact for law enforcement requests, and file a System Security and Integrity plan with the FCC.9Federal Communications Commission. Communications Assistance for Law Enforcement Act Most small ISPs meet this by buying a turnkey lawful intercept product that integrates with their core routers. Budget for it early; retrofitting after launch costs more and disrupts service.
On the copyright side, the Digital Millennium Copyright Act’s safe harbor shields you from monetary liability for infringing traffic sent through your network, but only if you meet its conditions. You must adopt a repeat-infringer policy, inform subscribers about it, and act quickly to remove or disable access to material once you receive a valid takedown notice.10Office of the Law Revision Counsel. 17 USC 512 – Limitations on Liability Relating to Material Online You must also register a designated agent with the U.S. Copyright Office to receive takedown notifications and publish that agent’s contact information on your website.11U.S. Copyright Office. DMCA Designated Agent Directory Skipping the agent registration is one of the most common and easily avoidable mistakes new ISPs make. Without a registered agent, you lose the safe harbor, and a single copyright suit can dwarf annual revenue.
Pole Attachments, Rights-of-Way, and State Registration
Aerial cable means pole attachment agreements with every utility that owns poles along your route. Federal law gives cable and telecommunications providers the right to attach at regulated rates, capped at a formula based on the percentage of usable pole space your attachment occupies, multiplied by the utility’s pole cost.12Office of the Law Revision Counsel. 47 USC 224 – Pole Attachments Annual per-pole rentals typically land in the single digits to low tens of dollars, but application and make-ready charges can dominate the upfront cost.
Many poles are jointly owned by an electric utility and a telephone company, so you may need separate approvals from both. Each application usually triggers a pre-construction survey, taking 30 to 90 days. Make-ready work to rearrange existing attachments and bring poles up to code before your cable goes up is billed to you and can run hundreds of dollars per pole in congested areas. This is where small ISP buildouts stall most often. Start pole attachments months before you plan to string cable.
For underground construction, you negotiate access to public rights-of-way with the relevant municipality. Many cities charge franchise fees based on a percentage of your gross revenue from customers in their jurisdiction, commonly between zero and five percent. Fees and permit timelines vary widely, so contact local public works early.
Most states also require telecommunications providers to register with the state public utility commission or equivalent agency before offering service. Forms, fees, and timelines differ by state; some charge a flat registration fee, others assess an annual fee based on revenue or access lines. Failing to register can bring fines and block lawful operation in that state.
Stand Up Operations Before Launch
Two software systems need to be running before your first subscriber signs up. An Operations Support System handles provisioning, network monitoring, bandwidth tracking, and alerting. A Business Support System handles subscriber management, plan selection, invoicing, payment processing, and tax calculation.
Taxes are more complex than most new ISPs expect. Depending on your service mix and jurisdictions, you may collect and remit a combination of federal, state, and local telecommunications taxes, plus USF surcharges passed through to customers. Your billing platform has to calculate these correctly on every invoice. Errors compound into audit liability.
Draft a Terms of Service agreement and an Acceptable Use Policy before launch. The Terms of Service govern the contractual relationship, including service levels, billing disputes, and limitation of liability. The AUP sets the rules for network use and gives you the basis for suspending accounts engaged in abuse, spam, or illegal activity. Have both reviewed by an attorney who works in telecommunications. These documents are the legal scaffolding you rely on when a subscriber dispute escalates or a law enforcement request lands.
Routing Security and Subscriber Defense
Securing your BGP sessions prevents route hijacking and accidental route leaks that can send your subscribers’ traffic through a third party’s network. The Mutually Agreed Norms for Routing Security framework covers four areas: filtering announcements for accuracy, enabling source address validation to prevent spoofing, maintaining current contact information in routing databases, and publishing routing data so other networks can validate it.13Federal Communications Commission. Reporting on Border Gateway Protocol Risk Mitigation Progress These measures are voluntary but increasingly expected, and some transit providers will refuse to peer with networks that lack basic route filtering.
On the subscriber-facing side, plan for DDoS attacks, botnet activity from compromised customer devices, and DNS abuse. Deploy DDoS mitigation in-house or through a third-party scrubbing service, run DNS-based threat filtering, and set up an abuse desk with a publicly listed contact address. Complaints will arrive from day one, and prompt handling keeps you off blacklists that would degrade service for every subscriber.
Net Neutrality Status
There are no binding federal net neutrality rules right now. The FCC’s April 2024 order restoring prohibitions on blocking, throttling, and paid prioritization was vacated by the Sixth Circuit in January 2025, which held that broadband internet access is an “information service” the FCC lacks authority to regulate as a common carrier under the Communications Act. Some states have their own net neutrality laws. If you plan any traffic management practices, review the laws in every state where you have subscribers.
Turn Up Service
With filings submitted, pole attachments approved, and the core network built, technical turn-up begins. Engineers stress-test upstream transit against projected loads to confirm the core routers do not drop packets, and routing policies are verified so traffic takes efficient paths and your BGP announcements are accepted by upstream providers and peers.
Subscriber activation starts with assigning IP addresses from your allocated blocks and provisioning each customer through the OSS. Watch traffic patterns closely in the first weeks. Real usage exposes misconfigured routes, undersized links, and coverage gaps that were invisible on paper, and adjustments will be needed. No plan survives first contact with real subscribers unchanged.
Once the first customers are online, the business begins in earnest. Billing cycles run, BDC deadlines start counting, and support tickets appear. Having your OSS, BSS, abuse desk, and compliance calendar fully operational before the first activation is the difference between a rocky launch and one you cannot recover from.
