🇺🇸United States

The US is not one network

Most "global" proxy networks treat the United States as a single region with a flag next to it. That's a useful abstraction for a sales deck and a terrible one for detection bypass. The US is five overlapping networks — fixed cable, fixed fiber, fixed DSL, mobile, and satellite — and each one routes differently, peers differently, and carries different fingerprint signals on the same IP-geo lookup.

A Chicago exit on Comcast Cable (AS7922) hands off traffic to the target's network at Equinix Chicago CH2 or the Chicago Internet Exchange. A "Chicago" datacenter IP probably exits at Ashburn or 1 Wilshire and gets reverse-routed inward. Commercial geo-IP databases rightly flag those two routes as different classes of network presence, and every serious retail and ad-tech fingerprint stack consumes those databases as inputs.

That is the problem Proxaro is narrow enough to solve. We don't sell a US pool alongside 120 other country pools; we only sell the US, sized deep.

The backbone you're actually riding

US internet transit is dominated by a handful of Tier-1 carriers — Lumen/CenturyLink, Zayo, Cogent, NTT, GTT, and Arelion. Nearly every American residential packet ends up on one of those backbones at least once. The peering happens in a small number of meet-me rooms:

• Ashburn, VA (Equinix DC1–DC15, plus the MAE-East legacy footprint) — still the densest peering fabric in North America and the eastern exit for most cable carriers.
• 1 Wilshire (Los Angeles) — the West Coast equivalent, where most US west-coast residential traffic hands off into targets hosted on AWS us-west-2 or any Cloudflare LAX edge.
• Equinix Chicago CH1–CH4 — the Midwest pivot, serving Comcast and RCN backbones for most of Illinois, Indiana, Michigan and Wisconsin.
• Equinix Dallas DA1–DA11 — the South-Central crossroads, carrying AT&T, Spectrum Texas, and a majority of the Verizon LTE traffic that clears CGNAT in the state.

A consequence of this geography: when a target runs MaxMind GeoIP2 City against your exit, the answer is a combination of the announcing ASN and the BGP path to the target. An IP announced from Comcast's Chicago allocation with a BGP path that lands at CH2 is statistically a Chicago user. The same IP re-announced by a datacenter in Texas is not — and the databases know.

What the big-six carriers actually cover

Residential ISP coverage in the US is not uniform. As of the FCC's 2024 broadband report:

• Comcast (AS7922) — ~32M subscriber addresses. Dominant across the Northeast, Mid-Atlantic, Chicago metro, Denver, and parts of the Southeast.
• Charter/Spectrum (AS20115, AS11427) — ~30M. Dominant in Texas, Florida, upstate New York, the Carolinas, and most of California outside SF/LA metros.
• AT&T Fiber + U-verse (AS7018) — ~14M. Deep in Texas, California, and the I-95 corridor.
• Cox (AS22773) — ~6M. Arizona, Oklahoma, Rhode Island, the Virginia Beach corridor.
• Frontier (AS5650) — ~3M. Appalachia, rural California, and pockets of the Great Lakes.

On mobile, T-Mobile (AS21928), Verizon Wireless (AS22394), and AT&T Mobility (AS20057) each run CGNAT pools sized in the tens of thousands of subscribers per shared public IP. That's the detail that matters for drop-day automation: an IP block on a T-Mobile CGNAT address takes down ten thousand real customers, so no serious target blocks mobile IPs wholesale.

DMAs, not just cities

When an ad-tech target says "Chicago market," they usually mean Nielsen DMA 602 — which covers Cook, DuPage, Lake, Will, Kane, Kendall and McHenry counties, plus northwest Indiana. A proxy exit in Des Plaines and one in Hammond, Indiana are both "Chicago DMA." A proxy exit in Joliet is also Chicago DMA. A proxy exit in Rockford is not Chicago DMA.

Proxaro targeting is DMA-aware for the 50 largest markets and city-aware for the top 200 cities. When you ask for Chicago, you get 602 traffic — by default routing through Comcast or Spectrum Chicago allocations rather than suburban carriers that happen to resolve to "Chicago."

What the US pool is not for

We don't unlock primary ticketing on any plan — Ticketmaster, See Tickets, AXS, DICE. The BOTS Act enforcement posture in 2025 and into 2026 is materially different from what it was in 2016, and the downside for us and for you is not worth the ARR. We also gate sneaker retail domains behind a written request during declared on-sale windows; talk to us before a drop.
