v2.4.0

Minor Changes

• #21 dcedeb5 Thanks @ro80t! - Add ASN 396319 (Oxylabs proxy network) to PROXY_ASN_PROVIDERS. Verified against RIPEstat and ipinfo.io whois data before inclusion.

v2.3.0

Minor Changes

• #17 7692147 Thanks @ro80t! - Add anonymousIp Hono middleware (anonymous-ip/hono) that runs checkAnonymity for the request's client IP and exposes the result via c.get("anonymity").

v2.2.0

Minor Changes

• #13 f1f0d1f Thanks @ro80t! - Add ASN 209043 (IPRoyal proxy network) to PROXY_ASN_PROVIDERS.

v2.1.0

Minor Changes

• 78f29d2 Thanks @ro80t! - Add 4 more ASNs to VPN_ASN_PROVIDERS (Astrill VPN, WiTopia, IVPN) and 6 more to PROXY_ASN_PROVIDERS (HostRoyale in India, Alsycon B.V. in the Netherlands, Belcloud in Bulgaria, Cyberdyne S.A. in the AFRINIC region), further broadening geographic and provider-type coverage. Each entry was independently verified against RIPEstat whois data before inclusion.

• c74d2e5 Thanks @ro80t! - Add 3 more ASNs to PROXY_ASN_PROVIDERS: a second Rayobyte/Sprious LLC ASN, and two well-documented bulletproof hosting networks — Chang Way Technologies (Hong Kong) and Media Land LLC (Russia). Each entry was independently verified against RIPEstat/ARIN whois data before inclusion.

v2.0.0

Major Changes

• d5918fb Thanks @ro80t! - Breaking: AnonymityCheckResult now ties each flag to its provider field at the type level, and provider is renamed to vpnProvider for symmetry with proxyProvider.

  -provider: string | null;
  -proxyProvider: string | null;
  +// isVpn: true  -> vpnProvider: string
  +// isVpn: false -> vpnProvider: null
  +// isProxy: true  -> proxyProvider: string
  +// isProxy: false -> proxyProvider: null

  Once you've checked result.isVpn (or result.isProxy), TypeScript narrows vpnProvider/proxyProvider to string for you — no more provider !== null checks needed alongside the flag. Update any code reading result.provider to result.vpnProvider.

Minor Changes

• 013e303 Thanks @ro80t! - Add 9 more ASNs to PROXY_ASN_PROVIDERS, broadening geographic coverage beyond the initial seed set: Melbikomas UAB (Lithuania, proxy/data-collection infrastructure), DataImpulse (Softoria LLC), and bulletproof hosting/proxy infrastructure in Malaysia (Shinjiru), Ukraine (VAIZ Partner, E-Rishennya, FDN3), and Bulgaria (Roza Holidays, SS-Net). Each entry was independently verified against RIPEstat whois data before inclusion.

v1.0.0

Major Changes

• 32467dd Thanks @ro80t! - Breaking: Rename checkVpn to checkAnonymity and VpnCheckResult to AnonymityCheckResult. The function already reported Tor exit node status alongside the VPN/ASN check, which the old name didn't reflect, and more anonymization signals (e.g. proxy detection) are planned. Update imports:

  -import { checkVpn, type VpnCheckResult } from "anonymous-ip";
  +import { checkAnonymity, type AnonymityCheckResult } from "anonymous-ip";
  
  -const result = await checkVpn(ip);
  +const result = await checkAnonymity(ip);

  The shape of the result (ip, isVpn, isTor, provider, geo) is unchanged.

Minor Changes

• e385f90 Thanks @ro80t! - Add proxy ASN detection, mirroring the existing VPN ASN detection. src/proxy-asns.ts exports PROXY_ASN_PROVIDERS, isProxyAsn, and getProxyProvider; checkAnonymity now also returns isProxy and proxyProvider.

  Two ASNs previously listed only in VPN_ASN_PROVIDERS (CroxyProxy and Rayobyte, ASNs 201814 and 64267) were open/commercial proxy services rather than consumer VPNs, so they moved to PROXY_ASN_PROVIDERS: isVpnAsn/checkAnonymity().isVpn will now report false for these two ASNs, while isProxyAsn/checkAnonymity().isProxy reports true. A few ASNs that genuinely serve both purposes (Aeza Group, 1337 Services/EliteTeam, IP Volume inc) remain listed in both maps.

v0.4.0

Minor Changes

• 501ff88 Thanks @ro80t! - Add 10 more ASNs to VPN_ASN_PROVIDERS, broadening coverage beyond mainstream consumer VPN brands: PureVPN, hide.me, a second Datacamp/CDN77 ASN, two dedicated Tor-relay-operator ASNs (Foundation for Applied Privacy, FlokiNET), and a new "bulletproof/anonymity hosting" category (Aeza Group, 1337 Services/EliteTeam) frequently used to front VPN and proxy traffic. Each entry was independently verified against RIPEstat/ARIN whois data before inclusion.

v0.3.0

Minor Changes

• 2db8b58 Thanks @ro80t! - Expand VPN_ASN_PROVIDERS with 19 additional VPN/proxy/Tor ASNs, including smaller secondary ASNs used by already-listed providers (ProtonVPN, Mullvad, PIA, Opera VPN, etc.) and a few previously-unlisted providers (IPVanish, Windscribe, AzireVPN, PrivateVPN, VyprVPN, Speedify, HMA, CroxyProxy, Rayobyte). Each entry was independently verified against RIPEstat/ARIN whois data before inclusion.
