The IP Blocklist API will detect potentially malicious or dangerous IP addresses.
Use this API for identifying malicious hosts, anonymous proxies, Tor, botnets, spammers and more.
Block, filter and flag traffic to help reduce attacks on your networks and software.
IP blocklist will detect the following main categories of IP addresses:
- Open proxies
- Tor nodes
- Malware servers
- Attack sources
- Criminal netblocks
- Malicious spiders
- Bots and botnets
- Exploit scanners
- Brute-force crackers
- Spam hosts
- Phishing hosts
Under the hood there are 3 core components that make up our blocklist system.
This is our system of automated bots, crawlers and honeypots which continuously collect data from across the Internet.
This system aggregates IP data from commercial and open-source security appliances.
This includes feeds from firewalls, gateways and intrusion detection systems (IDS).
We collect data from many public sources of IP related data.
This includes public blocklists, blacklists, malware/botnet trackers and various security intelligence feeds.
You can also download the complete IP data for direct use on your own systems using the Download API
IP blocklist is a database of known malicious IP addresses, this does not generally include commercial/legitimate VPN providers.
