IPdeny compiles raw data from regional internet registries and offers free of charge country IP address block downloads. Our country IP zone files can be easily used in your applications and web sites to minimize on-line fraud, SPAM, floods or brute force attacks. IPdeny country IP block files can be used to set-up firewall or packet filter rules to disable specific service access and ports based on a specific country.

Please note that we are not a blacklist - IPDeny.com provides downloads of country IP block allocations that are processed from public Internet IP address registries. We have no control over any services or any companies that use our IP country block files to block data or use custom access control. Please contact these providers directly for any assistance you require.

You can use our free on-line tools to automatically generate iptable, ipfw, ipchains and ACL rules for your server or router.

IPdeny is a completely free and public service. We welcome you to link back to our web site and to comply with our usage limits so that we can offer free and quality service to anyone.
