Common Questions

How often is your premium database updated?

For licensed members our database is updated every 4 hours (or 6x daily). Some competitors update only every 30 to 60 days or more.

How accurate is your country blocking data?

A recent audit revealed an accuracy rate of 99.8%.

What countries should I block?

The decision on what countries to block or allow will depend entirely on where you are doing business in the world. So the choice is yours. Recent trends tend to show heavily malicious traffic being generated from Brazil, China, Germany, Korea, India, Pakistan, Turkey, Romania, Russia, Ukraine, Venezuela, and Viet Nam. Certain networks in the United States are also major spam producers.

Is it best practice to block or allow a country?

If, for example, you are needing to block all traffic outside the US or outside your country, we recommend choosing to block or allow based on the resultant size of the Access Control List (ACL).

In other words, if you choose to only allow traffic from a single country, you are probably better off creating an access control list to allow only that country. If you want to block a specific country, you are generally better off to create an ACL block list.

Geo blocking on a firewall or web server?

You can use our geo blocking data to secure your server or firewall with a data license.

How many licenses do I need to secure my network?

A license is required for each firewall or server where our data will be stored or used to protect.
Your first license covers 1 server or firewall + 1 bonus firewall.
Each consecutive license secures 1 additional server or firewall.

May I resell, redistribute, give away or use your data elsewhere?

No, you may not. Doing so without the express written consent of Country IP Blocks, LLC is copyright infringement and a violation of our license agreement.

Will the use of .htaccess Access Control Lists slow down my server?

The answer to this question depends on the conditions of your server. Newer servers, with a reasonable amount of RAM probably will not notice a pereceptible slow down. However, if you are in a shared hosting environment you should check with your hosting provider.

How many Access Control List file formats do you offer?

Presently 19 distinct formats: 1) Apache .htaccess Deny, 2) Apache .htaccess Allow, 3) CIDR, 4) Cisco ACL, 5) Cisco bit bucket, 6) Decimal/CIDR, 7) Inverse Netmask, 8) JSON Allow, 9) JSON Deny, 10) Juniper Junos, 11) Linux iptables, 12) MicroTik, 13) Netmask, 14) network-object, 15) PeerGuardian2, 16) Web.config allow, 17) Web.config deny, 18) Custom CIDR, 19) Custom Netmask

As a paid member, how do I create and access our licensed data?

Those who have purchased licenses are given access to their own unique control panel. Within the control panel they can create their individualized Access Control List(s), aggregate ACL's, and chose to activate their unique URL. Activating your unique URL(s) will cause your data to automatically generate when we do our data updates every four hours. You can access these lists (aggregated and non-aggregated) through your unique URL(s).

Why is it important to aggregate networks in an Access Control List?

Many countries contain a large amount of networks. For example, as of March 29, 2019, the United States has nearly 70,000 public networks. ACLs of this size may be difficult to handle and tax system resources on older, less powerful firewalls and servers. Aggregation combines the networks into as few possible contiguous network ranges and then completes the process by creating the fewest number of legal networks. By aggregating an ACL for the United States, we can reduce the size of the ACL by over sixty-percent. This is significant as it takes up less space on your firewall or server and is much easier to process. Aggregation is only available for those who have purchased licenses.
