US Mobile IPs for AI TestingConsumer-Like, Sticky, WebRTC-Safe Proxies
Run accurate AEO audits that mirror real U.S. users with consumer-like 4G/5G devices, sticky sessions, rotation control, and WebRTC-safe configuration for reproducible AI answer testing.Technical infrastructure guide for teams running geo-specific AI visibility testing.
Why Mobile Can Be Better for AI QA
Consumer-Like Signals
Mobile carrier ASN + CGNAT mimic real users; often lower-friction on targets that filter datacenter IP ranges. Some AI endpoints and CDNs work fine over datacenter IPs, so choice depends on the specific target's filtering behavior.

Reproducibility
Sticky sessions keep identity stable for panels; controlled rotation for freshness. Essential for longitudinal testing and comparative analysis.
Protocol Parity
OpenVPN/SOCKS5/HTTPS/HTTP/3 (QUIC); UDP support for real-time paths. Note: End-to-end HTTP/3/QUIC depends on the target service supporting it.
Reference: General QUIC benefits.
WebRTC-Safe Audits (Don't Leak the Wrong IP)
The WebRTC Leak Problem
WebRTC ICE/STUN can expose public/local candidates, revealing your real IP despite using a proxy. This risk is described in MDN's WebRTC/ICE/STUN documentation.
Use relay-only/safe profiles and validate with a leak test before runs.
Quick Checklist
The MobileProxies.org Network (Specs)
Physical Infrastructure
Physical devices, 4G/5G/LTE SIMs; 1 user per device (private).
IP Infrastructure
CGNAT carrier IPs, 10–100 Mbps typical (carrier-dependent). Unlimited bandwidth is a plan/policy characteristic; actual speed and throughput vary by carrier network conditions.
Protocols Supported
OpenVPN, SOCKS5, HTTP/HTTPS, HTTP/3 (QUIC); UDP yes.
Authentication
User/pass or IP whitelist.
Rotation Behavior
Manual/API/scheduled rotation; ~10–20 s downtime then fresh IP.
Session persists until rotation (carrier may change on its own—normal raw 4G behavior).
How Many IPs Can One Port Surface?
Each modem = one active endpoint at a time; rotation samples from large CGNAT egress pools.
Exact pool sizes aren't published—measure empirically per carrier/region; expect duplicates over time as you cycle through the available pool.
Reference: APNIC Blog on CGNAT behavior.
Practical Guidance
For AEO testing: track unique IPs per 24h window; rotate as needed to maintain freshness while preserving session stability for panel runs.

FAQs
Why mobile over datacenter?
Consumer-like signals (carrier ASN/CGNAT) and stable sticky sessions for longitudinal tests. Mobile IPs blend with legitimate user traffic patterns and are often lower-friction on targets that filter datacenter ranges. Some AI endpoints work fine with datacenter IPs, so the choice depends on target-specific filtering. Reference: Cloudflare Blog.
Can I add CA/UK/DE?
Yes—provision dedicated endpoints per region. Contact sales for multi-geo setup and pricing.
Does HTTP/3/QUIC help?
It can reduce HOL blocking on supported paths; results vary by app/network. Reference: General QUIC benefits.
What about WebRTC leaks?
Use relay-only/safe profiles; verify before runs with leak detection tools. Reference: MDN Web Docs.
How quickly can I rotate IPs?
Manual/API/scheduled rotation takes ~10–20 seconds downtime. Custom cadence available—configure based on your testing needs.
