US ISP Proxies in United States

Where ISP fits in a US-only stack

4G and residential are the workhorses of a US automation stack. ISP is the specialist — a dedicated static IP announced under a real US residential ASN, useful exactly when the job needs the same identity for longer than residential can hold, and a human-looking ASN the way residential does.

You don't build a workload around ISP first. You reach for it when:

• A SNKRS queue token or a Shopify Plus checkout session will outlive a 60-minute residential sticky window.
• You're running multi-hour account warmups where IP consistency matters more than IP diversity.
• The target whitelists source IPs, and you need a stable handful rather than a rotating pool.
• You need sub-50ms latency to a US target and residential's 150–300ms is hurting your timing.

For everything else, 4G and residential are cheaper and better.

What our "ISP" IPs actually are

A Proxaro ISP IP is a server we operate in a US datacenter, whose IP is announced to the public internet from a residential ISP's ASN. The announcement is real — not a laundered BGP path, not a spoofed AS_PATH pretending to be residential. We have direct peering relationships with the Comcast, Spectrum and AT&T allocation desks; every IP we sell against those ASNs is genuinely theirs.

The implication for detection: the target's MaxMind, IPQS or Spur lookup returns the ISP name correctly, and the BGP trust graph matches what a clean residential peer would return. That is the whole point.

Pool sizing and availability

ISP is inventory-constrained in a way residential is not. Current US availability as of April 2026:

• Comcast (AS7922) — ~900 available IPs across NYC, Boston, Philadelphia, Chicago and Atlanta.
• Spectrum (AS20115) — ~1,400 across LA, Dallas, Orlando, Charlotte and upstate NY.
• AT&T (AS7018) — ~600 across Dallas, Houston and San Antonio.

Orders up to 50 dedicated IPs ship within a business day. Above 50, we schedule with the upstream carrier and typical lead time is 3–5 business days.

Pricing and inclusion

On Coast Plus, 25 dedicated ISP IPs come included in the plan. On Network (enterprise), volume is negotiated. On Local and Coast, ISP is an add-on billed per-IP-per-month — $8/IP for Comcast and Spectrum, $11 for AT&T (reflects our own wholesale cost difference). Bandwidth is unmetered inside your plan, which makes ISP disproportionately cheap for high-throughput work against a small surface.
