  Abuse reports (abuseipdb)

  Confidence 38%, 10 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.

• −15

  Proxy IP

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

  What it means

  A source marks this address as a proxy exit without saying whether it is a VPN, a datacenter proxy or something else.

  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, so it counts at half weight.

  Can it be fixed

  These labels are usually applied to whole ranges and are hard to clear by behaviour; moving to an unlabeled range is the practical fix.

• −12

  Blocklist hit: s5h.net

  Listed by s5h.net

  What it means

  This IP is on a public blocklist. Most lists record addresses that sent spam or took part in scanning or attacks.

  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

  A single aggregate list is moderate evidence, so about a dozen points; the email scenario more than doubles it because receiving servers query these lists directly.

  Can it be fixed

  Every list has a removal process, provided the cause is gone; some delist automatically after a quiet period.

• −10

  3 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.

• −5

  No rDNS record

  No PTR record; IPs allocated by established carriers usually have one

  What it means

  This IP has no reverse hostname (PTR record). Addresses allocated by established carriers usually have one.

  Which uses care

  Cares most: Email sending

  Why it is weighted this way

  A few points only: a missing PTR is a weak "unknown origin" signal, not a stain. Email cares more, since receiving servers check it.

  Can it be fixed

  Most hosts let you set a PTR in the control panel; set it to a sensible hostname.

• −4

  2 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-2023-44487

  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.

• −3

  IP type: Business broadband

  Business broadband is broadly trusted, though a small share are proxy exits

  What it means

  A business broadband address: generally trusted, though some corporate exits are used as proxies.

  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 deduction meaning "slightly less certain than residential".

  Can it be fixed

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

• +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.

• +6

  Spamhaus ZEN: residential range declaration

  PBL — range judged dynamic by Spamhaus

  What it means

  Spamhaus PBL declares this range as dynamic residential space that should not send mail directly. Not a stain: it is evidence of home broadband.

  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

  Counted as a bonus because it indirectly confirms a real access network.

  Can it be fixed

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

Listed on 1 of 8 blocklists checked: s5h.net.

• abuseipdb abuse confidence 38%, 10 reports in 90 days

Open ports observed: 22, 80, 443

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.
