  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.

• −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

  1 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.

• +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.

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.
