An original dataset for anyone who buys or studies residential IPs by network: who announces what, and which access technologies each large US city has.

**Quick answer — What does the US broadband IP index 2026 show?**

The index combines RIPEstat routing data (2026-10-18), company subscriber filings and the FCC National Broadband Map (December 31, 2025 data) for 35 US ISPs and 45 large cities. AT&T and Comcast announce the most IPv4 space; fiber reaches 93.5% of homes in Kansas City but 13.4% in Baltimore. Published by **Broadband Proxies**, free to cite.

## What are the key findings?

- **AT&T and Comcast run the largest home networks by address space.** Their listed ASNs announced 96,429,312 and 68,238,848 IPv4 addresses on 2026-10-18, per RIPEstat.
- **15 of the 35 ISPs use more than one ASN.** Spectrum alone keeps ten in our list, from AS20115 to former Time Warner Cable and Bright House networks.
- **Fiber availability ranges from 93.5% (Kansas City) to 13.4% (Baltimore)** of residential units across our 45 cities; the median is 62.2%.
- **Cable is near-universal:** the median city has cable available to 95.5% of residential units.
- **Gigabit service (1,000/100 Mbps) is widest in Pittsburgh (99.3%)** and narrowest in Columbus and Richmond (38.7%).
- **Comcast reports service to at least half of the homes in 22 of our cities, Charter Spectrum in 17, and AT&T in 44.**
- **Ownership moved faster than routing in 2026:** Cox (Charter since August 19), Frontier (Verizon since January 20) and Quantum Fiber (AT&T since February 2) still announced their homes on their own ASNs on 2026-10-18.

## Which ISPs announce the most IPv4 space?

Total IPv4 addresses announced by the ASNs we list for each ISP, from RIPEstat routing status on 2026-10-18. A network's size is not the number of proxy IPs any seller has on it.

## How was the index built?

- **ASNs:** we searched RIPEstat and PeeringDB for each ISP, kept the ASNs whose registered holder matches the company, and read their routing status on 2026-10-18. ASNs that announced nothing that day are listed on ISP pages but count as zero.
- **Subscribers:** from each company's latest quarterly or annual filing, with the exact metric name; private companies publish none.
- **Cities:** the principal city of the 45 largest metro areas in the Census Bureau's Vintage 2025 estimates; provider and technology shares from the FCC National Broadband Map Area Summary for each Census place, data as of December 31, 2025. Satellite providers are left out of provider lists.
- **Limits:** FCC figures describe where providers say they can serve, not subscribers. Routing counts describe network size, not proxy pools.

## Can I reuse this data?

Yes. Cite "Broadband Proxies, US broadband IP index 2026" with a link to this page. The underlying sources (RIPEstat, FCC, Census, company filings) are public; check them for your own use. Corrections are welcome at support@broadbandproxies.com.

## US broadband IP index: FAQ

### Does a bigger network mean more proxy IPs?

Not necessarily. A residential pool depends on which home devices opted in through partner networks, not on an ISP's address space. Broadband Proxies does not publish IP counts per ISP: ASN availability varies by network, city and time of day; the checkout shows what is online, and no IP count per ISP is published.

### Why is Cox missing from the IPv4 ranking?

RIPEstat's routing-status query for Cox (AS22773) timed out repeatedly on 2026-10-18, so we left it unmeasured rather than estimate it.

### How often will the index be updated?

At least once a year, and after major mergers or a new FCC data release. Each update keeps the date of every source.

### Where can I target these networks?

Every ISP in the index can be targeted with `asn-<number>` on any Broadband Proxies residential plan, from $2.63 for 1 GB as of October 2026.
