3.5.80.0 — datacenter / hosting IP, not residential.

3.5.80.0 is not a confirmed VPN, but it is a hosting / datacenter IP — almost certainly not a real residential consumer device. Common origins are scrapers, automated browsers, or self-hosted VPNs running on a VPS.

3.5.80.0 is announced by AS16509 (Amazon.com, Inc.), located in United States. The holder of the announced BGP prefix 3.5.80.0/24 is AMAZON-02 - Amazon.com, Inc.. You can look up other IPs on the same network via the IPLogs ASN directory.

Yes for write traffic, no for read. Datacenter IPs are almost never real human users — block POSTs, throttle reads, but avoid hard 403s if you serve global traffic.

Cautious. This IP isn't on any threat-intel feed today, but it isn't a regular consumer connection either. Don't grant it residential-tier trust.

If you visited iplogs.com from your own connection and were flagged suspicious, the cause is one of: a VPN client on your device or network, a corporate proxy, a CGNAT pool that overlaps with VPN exits, an ISP-level DNS resolver routing through Cloudflare/Apple infrastructure, or your IP being on a published commercial-VPN relay list. The "Why this IP is flagged" section above lists every source that matched — that's the dispute trail.
