IP Reputation & Blacklist Checker

Instantly check if your IP is flagged in global abuse databases — and what it means for your privacy and email delivery.

What does this mean?

This check uses the AbuseIPDB database — a community-driven platform where network administrators report IP addresses involved in hacking, spam, DDoS attacks, and other malicious activity.

Want to check a different IP address — a suspicious visitor, or the source of spam? The WHOIS Lookup tool shows the owner, ASN, and abuse score for any IP or domain.

Understanding the Score

Rating	Score	What It Means
No threats detected	76–100%	No abuse reports found, or only a handful of low-confidence ones — statistical noise, not a real signal. Your IP has a clean reputation.
Low threat	26–75%	Some reports exist. This may affect access to certain services.
Blacklisted	0–25%	Heavily reported IP. Likely blocked by firewalls and security systems.

Why might my IP be flagged?

Shared IP: You share an IP with other users (common with ISPs, VPNs, mobile networks). Someone else may have caused the reports.
VPN or proxy: VPN exit nodes are frequently reported because many users share the same IP.
Tor Browser or Brave Tor mode: Tor exit nodes are shared by thousands of users worldwide and are heavily reported in abuse databases. The IP shown is not yours — it belongs to the Tor exit node. This is expected behavior and does not reflect your personal activity.
Dynamic IP: Your ISP may have previously assigned this IP to another user who was reported.
Business network: Corporate IPs can be flagged if any device on the network sent spam or was infected.

Using VPN together with Tor?

When you run a VPN alongside Tor, the IP visible to websites is always the Tor exit node — not your VPN's IP. However, VPN and Tor serve complementary roles: the VPN hides the fact that you are using Tor from your ISP, and prevents the Tor entry node from seeing your real IP address. This combination adds an extra layer of privacy at the network level and is used by people in high-censorship environments or with elevated privacy needs.

Will my emails land in Spam?

IP blacklists are not only used by websites and firewalls — mail servers use them too. When you send an email, the recipient's server may check whether your IP is listed in abuse databases. A high abuse score can cause your emails to be silently dropped or routed to spam.

When this is a real problem:

You run your own mail server and send emails directly from your IP
Your ISP assigned you an IP that a previous user had blacklisted for spam
You use a VPN whose exit node is blacklisted — your business emails may fail to deliver
Your company network had an infected device that sent spam in the past

When this is not a problem:

You send emails through Gmail, Outlook, Proton Mail or similar services — they use their own mail servers with their own IP addresses, so your home or office IP does not affect delivery

Important note: AbuseIPDB — the database used on this page — is a general abuse reporting platform, not a dedicated email blacklist. A high score here is a strong signal that your IP may also appear on email-specific blacklists such as Spamhaus or Barracuda, but the two are not identical. If email deliverability is your primary concern, check those databases directly.

How to Fix a Flagged IP?

Contact your ISP to request a new IP address
Use a reputable VPN to change your exit IP — or switch to a Dedicated IP VPN for a clean, private address assigned only to you
If you run a server, check for malware or compromised services
Submit a self-report to AbuseIPDB to provide context

Is a website blocking your whole network, even though your IP looks clean? Read the guide to "Your network (ASN) has been flagged for abuse" and how to get back in.

The Verdict: What Your Score Really Means

Clean IP (0%) — You're good. No abuse reports found. No action needed — though this can change over time if your IP is shared or reassigned by your ISP.

Flagged IP? Don't panic. A high score rarely means you did something wrong. Shared IPs, recycled ISP addresses, VPN exit nodes, and Tor are flagged by default — not because of your personal activity.

The fastest fix: A VPN with a clean exit IP. For the best reputation long-term, look for providers that offer a Dedicated IP — a fixed address assigned only to you, with no history from other users.

Frequently Asked Questions

What does it mean if my IP address is blacklisted?

An IP blacklist (or blocklist) is a database of addresses flagged for suspicious activity like spam, malware, or botnet behavior. If your IP is listed, you might experience rejected emails, blocked website access, or frequent CAPTCHA challenges. Being listed doesn't always mean you did something wrong — ISPs frequently recycle IP addresses, and you may have inherited a "dirty" one from a previous user.

How do IP addresses end up on blacklists?

IP addresses get blacklisted when they are reported for sending spam, hosting malware, participating in DDoS attacks, or brute-force login attempts. Reports are submitted to databases like AbuseIPDB, Spamhaus, and SORBS by network operators, email providers, and security researchers. VPN exit nodes and Tor relays are almost always listed, as they're used by many different people including bad actors.

How does a blacklisted IP affect me in practice?

The most common impact is email: messages sent from a blacklisted IP may be rejected outright or land in spam folders. Certain websites and services use IP reputation databases to block access or require additional verification (CAPTCHAs). If you run a mail server, a blacklisted IP can severely disrupt email delivery. For regular home users, the main effects are typically failed email delivery and CAPTCHA challenges on websites.

How do I get my IP removed from a blacklist?

Most blacklist operators provide a removal (delisting) form on their website. Visit the specific blacklist that flagged your IP and follow their removal process — usually submitting a request with your IP and an explanation. For Spamhaus, visit spamhaus.org/lookup. For AbuseIPDB, flag the reports as inaccurate. Note that if you have a dynamic IP from your ISP, simply disconnecting and reconnecting may give you a new, clean IP address.

Why is my IP blacklisted even though I haven't done anything wrong?

This is common with dynamic IP addresses. ISPs recycle IP addresses — your current IP may have previously been assigned to someone who was running spam software, a botnet, or an open mail relay. VPN and proxy users face this constantly, as VPN exit IPs are shared among thousands of users and are almost universally blacklisted. If your IP is flagged incorrectly, request delisting — most databases process legitimate requests within 24–48 hours.

Does a VPN fix a blacklisted IP?

Not usually — and it can make things worse. VPN exit IPs are shared by thousands of users and are among the most heavily blacklisted addresses on the internet. While a VPN hides your home IP, you'll likely face more CAPTCHAs and blocked services, not fewer. The exception is a dedicated IP, sold as an add-on by some VPN providers: only you use it, so it carries no reports from other users. It still comes from a data center, though, so sites that block VPN networks may keep challenging you.
