About StarHub Ltd
StarHub Ltd (AS4657) is registered with APNIC in Singapore and was allocated on 1996-01-18. Self-declared in PeeringDB as a Network Service Provider (transit / backbone). IPLogs treats PeeringDB NSPs as core infrastructure (asn_peeringdb_nsp, zero weight) rather than hosting — large carriers in this bucket also carry residential traffic, so per-IP checks decide the verdict. PeeringDB lists it in 1 facility.
How IPLogs classifies AS4657
When the detection engine sees an IP that routes through AS4657, 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.
