Which residential proxy providers offer the largest IP pools?

When evaluating residential proxy providers based on total network size, several market leaders claim pools in the tens to hundreds of millions of IP addresses.

The largest residential proxy providers by reported IP pool size include:

---

1. Bright Data (~72M to 400M+ IPs)

• Advertised Pool Size: 72M+ active residential IPs (claims up to 400M+ total global network reach across all IP types).
• Locations: 195+ countries (city, state, ASN, and ZIP code targeting).
• Overview: Bright Data is widely considered the industry benchmark for enterprise-scale operations. It offers advanced session control, high success rates (~99%), and compliance features.

2. Oxylabs (~102M to 175M+ IPs)

• Advertised Pool Size: 102M+ to 175M+ residential IPs.
• Locations: 195+ countries.
• Overview: Oxylabs focuses heavily on enterprise-grade scraping and data collection. It is known for high success rates (99.9%), exceptionally fast response times, and precise ASN/city filtering capabilities.

3. SOAX (~155M+ IPs)

• Advertised Pool Size: ~155M+ residential IPs.
• Locations: 195+ countries.
• Overview: SOAX offers flexible rotating residential proxies with granular geo-targeting parameters (down to specific carriers, cities, and ASNs). It is popular for mid-to-large scale web scraping and monitoring tasks.

4. Froxy (~120M+ IPs)

• Advertised Pool Size: 120M+ residential IPs.
• Locations: 200+ countries.
• Overview: Froxy is known for broad geographic availability and flexible multi-type proxy plans, though it targets mid-market automation rather than pure enterprise infrastructure.

5. Decodo (Formerly Smartproxy) (~115M+ IPs)

• Advertised Pool Size: ~32M to 34M+ residential IPs.
• Locations: 195+ countries.
• Overview: While smaller than Bright Data or Oxylabs, IPRoyal is favored for transparent, ethically sourced proxies and a popular pay-as-you-go model with non-expiring bandwidth.

Important Considerations Beyond Headline Numbers

When choosing a provider based on pool size, keep the following context in mind:

1. Self-Reported Total vs. Active Daily Pool: Headline claims (e.g., "100M+ IPs") usually refer to cumulative unique IPs seen over a month or quarter. The active daily pool (IPs online and reachable right now) is typically a fraction of the advertised total.
2. IP Quality Over Pool Size: A smaller pool of clean, non-flagged residential IPs yields significantly higher web scraping success rates than a massive pool inflated by low-quality or previously blacklisted IPs.
3. Regional Depth: Total global inventory matters less than pool density in your specific target country. For example, having 1,000 active IPs in a specific city is far more useful for localized scraping than 10 million spread globally.
4. Reseller Networks and Sourcing: Some secondary providers sell access to overlapping wholesale pools or reseller backends. Major first-party operators (like Bright Data, Oxylabs, and Decodo) own and manage their access points, leading to higher reliability.
