IPdeny compiles raw data from regional internet registries and offers complete country IP block downloads for on-line users. Our country IP zone files can be easily used in your applications and web sites to minimize on-line fraud, SPAM, floods and brute force attacks. IPdeny country IP block files can be quickly adapted to set-up in firewalls or packet filters to disable specific services and ports from the countries you do not welcome.
Please note that we are not a blacklist, we just provide country IP block allocations from public IP registry records. We have no control over services or companies that use our IP country block data - contact these providers directly.

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 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 on our planet.

You can easily create a brand new web site from ready made templates. See it for yourself how easy is to diy web design.

We got an email from Cusimano.com person suggesting us to use CIDR zone file merging script from zwitterion.org. We have ran a few in-house tests and this Perl based script effectively decreases CIDR IP block count up to 60% or even more. The less firewall rules you have set-up in your packet filter (server or [...]
