Frequently Asked Questions

What is the fundamental difference between IPLC, IEPL, and public VPNs?

IPLC (International Private Leased Circuit) and IEPL (International Ethernet Private Line) are dedicated, physical point-to-point fiber optic lines leased from telecommunications carriers. They do not cross the public Internet gateway or national firewalls (GFW). Standard public VPNs tunnel through public ISP routes and are prone to throttling, jitter, and deep packet inspection (DPI) blocks.

Why do so many commercial streaming services block datacenter VPN IPs?

Platforms like Netflix, Disney+, and OpenAI continuously cross-reference incoming client IP addresses against Autonomous System Number (ASN) registries. Hosting and cloud ASN subnets (such as AWS, DigitalOcean, Hetzner) are flagged as non-residential. Our curated providers offer native residential ASN exit nodes or dedicated clean IP segments that bypass automated bot checks.

How do you verify the technical specifications of these proxy providers?

Our engineering team monitors latency, ping jitter, and packet loss using continuous ICMP and HTTP/3 probes across peak hours (8 PM - 11 PM CST). We independently confirm media unlocking, protocol support (Shadowsocks, VLESS, Trojan, Hysteria 2), and refund responsiveness before listing.

Are affiliate links changing the price I pay?

No. The prices displayed are the exact prices charged by the providers, or lower when using our verified coupon codes (e.g. "AMM", "firefly", "yxr888"). Our referral commission is paid directly by the partner out of standard marketing budgets.
