US ISP Proxies at Datacenter Speed
22,000+ US ISP-hosted residential IPs with high trust scores and ~39 ms response times — built for work that needs to look real and run fast.

Why US ISP Proxies
FlashProxy Shared ISP Proxies are residential IPs hosted on real US internet service provider networks, so they carry the trust score of a home connection while delivering datacenter-grade speed. Targets see a legitimate US residential IP, not a flagged datacenter range, which means fewer blocks and CAPTCHAs. The pool spans 22,000+ US ISP addresses, giving you room to spread requests across many distinct IPs. You get the credibility of residential and the throughput of a server in one product. Every IP is US-based — ideal when your traffic must originate inside the United States.
What You Can Do With Them
This combination of trust and speed suits any workflow where a target scrutinizes the IP before letting you act. Sneaker checkouts, social media account management, and other account-heavy tasks benefit from IPs that read as ordinary US households. Because the IPs are stable and fast, you can keep long sessions alive without the lag or disconnects that sink time-sensitive jobs. High trust scores reduce verification friction, so accounts stay logged in and checkouts complete. If your work fails on datacenter IPs but feels slow on standard residential, US ISP proxies close that gap.
US Scale and Performance
Performance is the reason ISP proxies exist: typical response time is around 39 ms, fast enough for real-time browsing, automation, and checkout flows. The network handles up to 9,000 concurrent connections, so you can run large parallel jobs without queuing. With 22,000+ US IPs behind that capacity, you can distribute load widely and avoid hammering any single address. Whether you are scraping at scale or managing hundreds of accounts, throughput stays consistent across the US footprint. This is residential trust without the latency penalty that residential pools usually impose.
Static (Sticky) vs Rotating Sessions
FlashProxy offers both static (sticky) and rotating sessions on the same US ISP pool. Static sessions hold one IP for the life of the session — the right choice for logins, checkouts, and any task where a changing IP looks suspicious. Rotating sessions cycle through the pool so each request can use a fresh IP, which spreads your footprint across large scraping jobs. Pick sticky when continuity matters and rotating when coverage matters. You control the behavior per connection, so a single account can use both modes for different tasks.
Setup: HTTP, SOCKS5 and Authentication
Setup is standard host:port with user:pass authentication, so the proxies drop into any tool that speaks HTTP or SOCKS5. Both protocols are supported, and SOCKS5 includes UDP ASSOCIATE for workloads that need UDP rather than plain TCP. Point your browser, scraper, or bot at the endpoint, supply your credentials, and choose sticky or rotating. No special client is required. Because authentication is per-credential, you can issue and manage access without touching IP allowlists, which keeps configuration simple across multiple machines.
Pay-As-You-Go Pricing
Pricing is pay-as-you-go per gigabyte, starting at $1.20/GB and scaling down to a $0.20/GB volume floor as your usage grows. You pay only for the bandwidth you move, so light testing stays cheap and heavy production work earns the lower rate. There are no per-IP fees on the shared pool — the 22,000+ US IPs are available within your bandwidth. This makes it easy to start small and scale a single workflow up without re-architecting your billing. Higher volume simply lowers your effective cost per gigabyte.
