IPure IP purity check

IP purity report

16.76.121.32

40/ 100

High risk

confidence: high

Most platforms will add verification or block outright; consider replacing it.

Based on signals observed from public and partner data sources at 2026-09-30 14:15 UTC. This describes IP-level risk only; platforms' internal risk data is not visible to us.

Suitability

What it is good for

Each use case weighs the evidence differently; these are not one overall score.

AI services

ChatGPT · Claude · Gemini

19

Best avoided

Main issue: Known VPN exit

Least tolerant of data center and proxy exits: more likely to get degraded service, verification prompts or account limits. Spam history does not matter here

Social sign-up

X · Discord · Telegram · Reddit

20

Best avoided

Main issue: Known VPN exit

Sign-up is the strictest checkpoint: data center / proxy exits are more likely to be asked for phone verification or refused, and IPs with bulk-registration history are blocked far more often

Streaming / short video

TikTok · Netflix · YouTube

6

Best avoided

Main issue: Known VPN exit

Native IP and low sharing matter most: a broadcast IP reads as a region mismatch, and shared exits get throttled

Gaming platforms

Steam · PSN · Epic · Nintendo

9

Best avoided

Main issue: Known VPN exit

Region locks, regional pricing and gifting all follow the IP's location, so broadcast IPs tend to be treated as cross-region; data center exits carry a high risk of restrictions

Cross-border e-commerce

Amazon · eBay · Shopee

26

Not recommended

Main issue: Known VPN exit

Linked-account store closures are driven first by shared IPs, and only then by data center ranges

Email sending

SMTP · marketing email

54

Borderline

Main issue: Known VPN exit

Blocklists make or break deliverability, while sending from a data center IP is normal and is not penalised

Evidence

Why it got this score

  • −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.
  • −8

    Cloud provider range (AWS)

    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.
  • −6

    1 open ports

    Open ports: 443

    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.
  • −6

    rDNS looks like a server

    Reverse hostname ec2-16-76-121-32.ap-northeast-1.compute.amazonaws.com matches server naming

    What it means
    The reverse hostname follows server naming (server, vps, host and the like).
    Which uses care
    Cares most: Email sending
    Why it is weighted this way
    A light deduction: one more sign of "this is a server".
    Can it be fixed
    You can change the PTR in the host's panel, but it is only corroboration and barely moves the total.
  • −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.
  • −2

    Abuse reports (abuseipdb)

    Confidence 4%, 2 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.

What an IP check cannot tell you

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.
