▸ How the score works

The total is 100, the sum of the signals below. Every rule is listed here; there are no hidden factors.

Supported region	30	Full points if the exit country is on the official list; otherwise the verdict is 'Unavailable'. The country comes from the loc field of that site's Cloudflare edge.
IP type	25	Residential / mobile 25 (20 if guessed from the ASN name); business / education 18; unknown 12; datacenter 8; public VPN 5; Tor 0.
IP reputation	15	AbuseIPDB score 0 → 15, ≤25 → 11, ≤75 → 5, higher → 0; IPQS fraud score >30 −4, >75 −8; −2 per DNS blocklist hit (max −4). Neutral 8 when data is unavailable.
Timezone	10	Browser timezone matches the exit location 10; same UTC offset 7; mismatch 0; exit timezone unknown 5.
WebRTC leak	10	No other public IP exposed (or WebRTC disabled) 10; exposed IP in a supported region 6; unknown 5; in an unsupported region 0.
Browser language	5	First language matches the exit region 5; English first, or the region's language listed 3; otherwise 0.
Exit consistency	5	Same exit as this page 5; another route in the same country 4; different country 1; unreachable 0; IPv6 exit in an unsupported region 0.

≥80 Available · 60–79 Mostly OK · <60 High risk · unsupported exit region = Unavailable.

Not included

DNS leak: needs a self-hosted test domain with NS delegation, or sending your requests to a third-party service. Neither is in place, so we skip it rather than show a fake result.
The IPv6 exit is probed via Cloudflare's IPv6 address, falling back to the IPv6-only api6.ipify.org; if both fail we say there is no IPv6 exit. This site has no IPv6 itself, so it cannot compare IPv6 from its own server.
Partial-country exclusions (e.g. occupied regions of Ukraine) cannot be judged from a country code; check the official pages.

Supported-region lists come from the official pages, compiled 2026-11-02 (Beijing time): Anthropic Supported Regions · OpenAI Supported Countries

The score only reflects how well your current network matches the official region policies. It is for reference only and does not guarantee sign-up, payment or uninterrupted use; account checks also depend on payment methods and usage that this page cannot see.

Privacy: your browser requests claude.ai, chatgpt.com, 1.1.1.1 and its IPv6 address (Cloudflare), api6.ipify.org (only if the former fails), myip.ipip.net and STUN servers (Google, Xiaomi) directly to read your exits. This site only receives the same exit IP lookup as the IP Check page plus a local lookup of up to 4 other exit IPs; no browser environment data is stored.
