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.
Corpus over commodity flags
Trace Exit is built around an owned gaming-login corpus plus licensed enrichment. Public product fields stay ToS-safe; Server Armour can enrich internally under its sister license.
Latency budget
Login paths want cache hits. Design for stale-while-revalidate and shared singleflight on miss so wipe-day storms do not stampede upstream.
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.
