Commercial VPN products that route exit traffic through Proton AG. Any IP announced from this ASN is a confirmed VPN exit without requiring a probe.

How IPLogs classifies AS209103

When the detection engine sees an IP that routes through AS209103, it checks three lists: (1) the curated VPN-provider ASN list, (2) the datacenter / hosting ASN list, and (3) the trusted CDN allowlist. Matches produce one of vpn_asn, dc_ip, or no flag respectively. Keywords in the org name (e.g. "vpn", "proxy", "anonym") may also trigger vpn_org_keyword even for unknown ASNs.

Use the ASN as a shortcut when you want to block a whole hosting provider at the edge rather than maintaining a per-IP list.
