VPN detection for game servers
Login gates need to know whether a player is on a consumer ISP, a datacenter, or an anonymizer — without nuking cloud gaming or mobile CGNAT.
Why game platforms look up IPs
Multiplayer economies, region locks, and ban evasion all lean on network signals. A flat “proxy=yes” bit is noisy. Operators need tri-state privacy (true / false / unknown), datacenter vs residential, and a fraud score they can threshold per mode (strict PvP vs casual).
What to enforce at login
Kick or challenge when anonymizer is true or fraud score exceeds your policy. Soft-warn when the signal is unknown. Always carve out known cloud-gaming ASNs and document CGNAT so legit mobile players are not collateral.
Signals built for gaming traffic
Trace Exit combines gaming-login signals with licensed enrichment. Public product fields stay within the published API contract.
Keep login lookups fast
Login paths want cache hits. Prefer short TTLs with background refresh, and coalesce duplicate lookups on a miss so traffic spikes do not overwhelm the service.
FAQ
Does VPN detection block all proxies?
You choose the policy. Use privacy.anonymizer and fraud.score with allowlists for cloud gaming and trusted ASNs.
What about CGNAT?
Carrier-grade NAT shares addresses across many users. Prefer ASN guidance and avoid hard bans on mobile ranges without extra signals.
How do I try it?
Use the free checker for the same full nested lookup response (rate-limited), then create an API key for higher limits.
