  Blocklist hit: Spamhaus ZEN

  SBL — known spam source; SBL DROP — recommended to drop the whole range

  What it means

  A Spamhaus listing means this IP was confirmed sending spam, or the machine is compromised and being used as a relay.

  Which uses care

  Cares most: Email sending; Barely looks at it: AI services, Social sign-up, Streaming / short video, Gaming platforms

  Why it is weighted this way

  This is behavioural evidence, not a profile guess, so it is a hard cap and fatal for email. It carries little weight for scenarios that ignore mail reputation, such as AI services.

  Can it be fixed

  Fix the cause first (shut down the compromised service, remove malware), then request removal from Spamhaus; usually resolved within days.

• −25

  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.

• −10

  7 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.

• −4

  4 known vulnerabilities

  Mostly matched from software version banners; it shows the machine is unmaintained, and platform risk systems do not look at this directly: CVE-2025-23419, CVE-2021-3618, CVE-2023-44487 and more

  What it means

  Scanners matched the version banners of exposed services to published CVE numbers. Most are just version matches, not confirmed exploitable holes.

  Which uses care

  Barely looks at it: AI services

  Why it is weighted this way

  It shows the machine is unmaintained, another sign of "server"; platform risk systems never count CVEs on an IP. Capped at 8 points (20 before 2026-09-26, which pushed ordinary VPS into "very high risk" for one fact charged three times).

  Can it be fixed

  Update the system and the services exposed to the internet (sshd above all); scanners update within days, then re-check.

• −1

  Abuse reports (abuseipdb)

  Confidence 1%, 1 reports in the last 90 days

  What it means

  Someone reported this IP to an abuse database (AbuseIPDB), typically for SSH brute force, port scanning or comment spam. The reporter may have seen a program on this machine, or a previous tenant.

  Which uses care

  Cares most: Social sign-up, Email sending

  Why it is weighted this way

  Counted at half the database's confidence. Sign-up scenarios care most: IPs with bulk-registration or credential-stuffing history are their first priority to block.

  Can it be fixed

  Reports age out; with no new reports for 90 days the score drops. If your machine is the one scanning, check for implanted software first.

• +5

  Native IP

  Registered and used in the same country, allocated directly by a local carrier

  What it means

  Registered and used in the same country, allocated directly by a local carrier: a "native IP".

  Which uses care

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

  Why it is weighted this way

  A bonus: region-based checks will not trip.

  Can it be fixed

  An inherent attribute of the IP or its range; nothing a user can change short of a different IP.

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.
