AbuseIPDB

What it is

AbuseIPDB is a commercial IP abuse reporting and reputation service (abuseipdb.com). System administrators and security teams check IP addresses against a community-fed database of reported malicious activity and can submit abuse reports through the web UI or API.

What it helps with

- Checking visitor or attacker IPs for prior abuse reports before allowing or blocking traffic.
- Reporting spam, scanning, brute force and related abuse so others can defend their networks.
- Pulling blacklists and automating checks via the public API (including common Fail2Ban-style integrations).
- Tracking higher volumes of checks, reports and customisable blacklists on paid plans.
- Supporting firewall, WAF and SOC enrichment workflows with IP reputation context.
- Starting on a free Individual plan before upgrading for higher daily limits.

Who it's for

System administrators, webmasters and SOC analysts who need an IP reputation and abuse-reporting service as a lightweight peer to broader threat intelligence platforms.

Worth knowing

AbuseIPDB is freemium: a free Individual API tier (daily check/report limits) plus paid Basic and Premium plans with higher limits and support, as published on abuseipdb.com/pricing. Web lookups and API access require an account. Confirm current quotas on the vendor pricing page.
