  Blocklist hit: Spamhaus ZEN

  XBL — compromised host / open proxy; SBL CSS — automatically detected spam source; PBL — range judged dynamic by Spamhaus

  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.

• −19

  Abuse reports (abuseipdb)

  Confidence 37%, 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.

• −6

  2 open ports

  Open ports: 161, 6161

  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.

• −3

  Shared exit

  62 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.

• +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.

• +8

  IP type: Residential

  Residential broadband is the IP type risk systems trust most

  What it means

  A residential, mobile, education or government network address: the kind of source risk systems trust most.

  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 bonus: the vast majority of real people come from these networks, so the default stance is to let them through.

  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.
