ISP
Proxies
Datacenter speed, residential trust. IPs registered to real internet service providers, not cloud hosting. 50-120ms latency for high-volume data collection at $1/GB.
The ISP Sweet Spot
ISP proxies sit between datacenter and residential. You get the throughput of datacenter hosting with the legitimacy of ISP registration.
Ideal Workloads
Google, Bing, and other search engines rarely block ISP-grade IPs. Collect ranking data at volume with low latency and low cost.
Monitor thousands of news sites, blogs, and public forums. ISP proxies handle the volume without the cost overhead of residential.
Track pricing across retail sites that use moderate protection. ISP proxies deliver consistent results at half the residential cost for most targets.
Government sites, directories, job boards, and public databases. These targets rarely require residential-level trust, making ISP the cost-efficient choice.
Collect data from public APIs with rate limiting. ISP proxies provide the IP diversity needed to distribute requests without the residential premium.

Frequently Asked Questions
What exactly is an ISP proxy?
ISP proxies are IP addresses hosted in datacenters but registered to legitimate internet service providers. They appear in IP databases as belonging to companies like AT&T, Vodafone, or NTT rather than cloud hosting providers. This gives them higher trust scores than standard datacenter IPs while maintaining datacenter-level speed.
How fast are ISP proxies compared to residential?
ISP proxies average 50-120ms latency, roughly 2-3x faster than residential proxies (150-300ms). The speed comes from datacenter hosting with direct peering, while the trust comes from ISP registration. For high-volume workloads where every millisecond matters, the difference adds up fast.
Will ISP proxies work on sites that block datacenter IPs?
Most sites that block standard datacenter IPs will accept ISP proxy traffic. The IP is registered to an ISP, not a hosting provider, so it passes the most common IP classification checks. However, sites with the most aggressive protection (some e-commerce, social media) may still require residential or mobile proxies.
What is the cost difference between ISP and residential?
ISP proxies cost $1/GB compared to $2/GB for residential. For workloads that ISP proxies can handle (SERP scraping, news monitoring, public data collection), you get the same results at half the cost with better speed.
Can I geo-target ISP proxies to specific countries?
Yes. Set the "country" parameter to any supported two-letter ISO code. Spider will route through an ISP proxy in that country. Coverage spans 100+ countries, with the largest pools in the US, UK, Germany, Japan, and Brazil.
Are ISP proxies suitable for long-running sessions?
Yes. ISP proxy IPs are more stable than residential IPs, making them well-suited for sticky sessions. Set a session ID to maintain the same IP for up to 10 minutes, which works well for multi-page navigation and authenticated scraping flows.
