About Lumen (Level 3)
Tier-1 transit provider. Mixed traffic — residential and datacenter. Not automatically flagged.
How IPLogs classifies AS3356
When the detection engine sees an IP that routes through AS3356, 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.
