About FIRST SERVER LIMITED
FIRST SERVER LIMITED (AS205090) is registered with RIPE NCC in United Kingdom and was allocated on 2017-11-09. Not enough registry signal to classify the whole ASN. IPLogs still classifies individual IPs in it via MaxMind, reverse DNS, and active probing.
How IPLogs classifies AS205090
When the detection engine sees an IP that routes through AS205090, 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.
