  IP type: Hosting / data center

  Hosting / data center IPs are the main source of automated traffic

  What it means

  This IP sits in a hosting / datacenter range. Platforms assume real people browse from home or a phone, and machines live in datacenters.

  Which uses care

  Cares most: AI services, Social sign-up, Gaming platforms, Cross-border e-commerce; Barely looks at it: Email sending

  Why it is weighted this way

  The most basic signal there is: scrapers, bulk sign-ups and fake traffic overwhelmingly come from datacenters, so risk systems discount the whole range. It says nothing about what you did, only that you share the range.

  Can it be fixed

  The range type cannot be changed. What helps is not stacking other issues on top: stay off blocklists, close unneeded ports, avoid crowded exits.

• −20

  Known VPN exit

  Only 1 data source flags it as a VPN; the evidence is limited, so it counts at half weight

  What it means

  Commercial risk databases mark this address as a VPN server exit. Platforms see "someone on a VPN", not you.

  Which uses care

  Cares most: AI services, Social sign-up, Streaming / short video, Gaming platforms, Cross-border e-commerce

  Why it is weighted this way

  Only one source says so, and a single database can be wrong (public DNS resolvers have been mislabeled), so it counts at half weight. If a second source follows in a few days, this item doubles.

  Can it be fixed

  Self-hosted proxies on VPS ranges are often labeled block-wide; changing the IP is the only fix. Commercial VPN exits are labeled by design.

• −15

  Broadcast IP

  Range registered in US but used in JP (announced across borders)

  What it means

  The country the range is registered in differs from where it is actually used. Common when an international host uses a range registered in country A inside country B, or when a proxy vendor leases ranges.

  Which uses care

  Cares most: Streaming / short video, Gaming platforms; Barely looks at it: Email sending

  Why it is weighted this way

  Region-sensitive platforms (streaming, region-locked gaming) care most: they cross-check several geo databases and treat a mismatch as "wrong region". Little effect on scenarios that ignore region.

  Can it be fixed

  This is a registration attribute of the range and cannot be changed by the user. Platforms use different geo databases, so some may not notice at all.

• −10

  2 open ports

  Includes admin ports 22: clear evidence of a server rather than home broadband

  What it means

  Scanners see ports open on this IP. With admin ports such as 22 or 3389 it is almost certainly a server, not a home router.

  Which uses care

  Barely looks at it: AI services

  Why it is weighted this way

  Mainly corroboration that "this is a server", which the datacenter item already charged for, so only a few points here; AI-type scenarios weight it at 0.3 to avoid charging the same fact three times.

  Can it be fixed

  Close or restrict ports that do not need public access (firewall, non-default port, fail2ban); scanners update within days, then re-check. One of the few items you can change yourself.

• −8

  Cloud provider range (Linode)

  Public cloud IPs can be rented cheaply by anyone, so they rate below self-run data centers

  What it means

  The address falls inside a public cloud provider's published range; anyone can rent a machine in the same range within minutes.

  Which uses care

  Cares most: AI services, Social sign-up, Gaming platforms, Cross-border e-commerce; Barely looks at it: Email sending

  Why it is weighted this way

  A small extra deduction on top of the datacenter one: public cloud has a lower barrier than private hosting and abuse is more concentrated.

  Can it be fixed

  Range membership cannot be changed; different regions of the same cloud, or independent datacenters, are labeled differently.

• −3

  Shared exit

  57 devices observed in the same subnet

  What it means

  Many devices share this exit. Whatever others do on it gets attributed to you as well.

  Which uses care

  Cares most: Social sign-up, Streaming / short video, Cross-border e-commerce

  Why it is weighted this way

  Cross-border e-commerce and social sign-up care most: shared IPs are the leading cause of linked-account bans.

  Can it be fixed

  Move to a dedicated or low-share exit; sharing levels vary widely between plans from the same vendor.

Not listed on any of the 8 blocklists checked (Spamhaus ZEN, SpamCop, PSBL, blocklist.de, UCEPROTECT L1, s5h.net, DroneBL, SpamRats).

Each platform's internal risk labels

Platforms keep their own IP reputation data and ban records and do not publish them. No hit in public sources does not mean a platform has nothing on this IP.

Whether the IP is truly exclusive

Sharing is only the number of devices observed in the same subnet. It cannot show who else is using this exit right now, or what they are doing.

Which accounts this IP has been tied to

Account-to-IP links exist only inside each platform. Accounts previously banned on this IP are invisible to us.

Device, browser and behaviour

Risk systems look at IP + device fingerprint + behavioural rhythm together. A clean IP with an odd fingerprint or behaviour still gets blocked.

Whether the account profile matches the IP

When sign-up country, phone number, payment method, language or time zone disagree with the IP's location, platforms verify further. That is unrelated to IP purity.
