This plugin records the IP address of the original post author when a post first gets created.
The admin listing of posts is amended with a new “Author IP” column that shows the IP address of the author who first saved the post.
The plugin is unable to provide IP address information for posts that were created prior to the use of this plugin.

<h3>Hooks</h3>
The plugin is further customizable via four filters. Typically, code making use of filters should ideally be put into a mu-plugin or site-specific plugin (which is beyond the scope of this readme to explain).
c2c_show_post_author_ip_column (filter)
The ‘c2c_show_post_author_ip_column’ filter allows you to determine if the post author IP column should appear in the admin post listing table. Your hooking function can be sent 1 argument:
Argument :
<ul>
<li>$show_column (bool) Should the column be shown? Default true.</li>
</ul>
Example:
<pre><code>/**
 * Don't show the post author IP column except to admins.
 *
 * @param bool $show_column Should the column be shown? Default true.
 * @return bool
 */
function post_author_ip_column_admin_only( $show ) {
 if ( ! current_user_can( 'manage_options' ) ) {
 $show = false;
 }
 return $show;
}
add_filter( 'c2c_show_post_author_ip_column', 'post_author_ip_column_admin_only' );
</code></pre>
c2c_get_post_author_ip (filter)
The ‘c2c_get_post_author_ip’ filter allows you to customize the value stored as the post author IP address. Your hooking function can be sent 2 arguments:
Arguments :
<ul>
<li>$ip (string) The post author IP address.</li>
<li>$post_id (int) The post ID.</li>
</ul>
Example:
<pre><code>/**
 * Store all IP addresses from local subnet IP addresses as the same IP address.
 *
 * @param string $ip The post author IP address.
 * @param int $post_id The post ID.
 * @return string
 */
function customize_post_author_ip( $ip, $post_id ) {
 if ( 0 === strpos( $ip, '192.168.' ) ) {
 $ip = '192.168.1.1';
 }
 return $ip;
}
add_filter( 'c2c_get_post_author_ip', 'customize_post_author_ip', 10, 2 );
</code></pre>
c2c_get_current_user_ip (filter)
The ‘c2c_get_current_user_ip’ filter allows you to customize the current user’s IP address, as used by the plugin. Your hooking function can be sent 1 argument:
Argument :
<ul>
<li>$ip (string) The post author IP address.</li>
</ul>
Example:
<pre><code>/**
 * Overrides localhost IP address.
 *
 * @param string $ip The post author IP address.
 * @param int $post_id The post ID.
 * @return string
 */
function customize_post_author_ip( $ip, $post_id ) {
 if ( 0 === strpos( $ip, '192.168.' ) ) {
 $ip = '192.168.1.1';
 }
 return $ip;
}
add_filter( 'c2c_get_post_author_ip', 'customize_post_author_ip', 10, 2 );
</code></pre>
c2c_post_author_ip_allowed (filter)
The ‘c2c_post_author_ip_allowed’ filter allows you to determine on a per-post basis if the post author IP should be stored. Your hooking function can be sent 3 arguments:
Arguments :
<ul>
<li>$allowed (bool) Can post author IP be saved for post? Default true.</li>
<li>$post_id (int) The post ID.</li>
<li>$ip (string) The post author IP address.</li>
</ul>
Example:
<pre><code>/**
 * Don't bother storing localhost IP addresses.
 *
 * @param bool $allowed Can post author IP be saved for post? Default true.
 * @param int $post_id The post ID.
 * @param string $ip The post author IP address.
 * @return string
 */
function disable_localhost_post_author_ips( $allowed, $post_id, $ip ) {
 if ( $allowed && 0 === strpos( $ip, '192.168.' ) ) {
 $allowed = false;
 }
 return $allowed;
}
add_filter( 'c2c_post_author_ip_allowed', 'disable_localhost_post_author_ips', 10, 3 );
</code></pre>

Post Author IP

Records the IP address of the original post author when a post first gets created.

IP Location Block plugin that allows you to block access to your site based on the visitor location while also keeping your site safe from malicious attacks. The plugin brings a smart and powerful protection methods named as “WP Zero-day Exploit Prevention” and “WP Metadata Exploit Protection“.
Combined with those methods and IP address geolocation, you’ll be surprised to find a bunch of malicious or undesirable access blocked in the logs of this plugin after several days of installation.
Note: This plugin is based on the now abandoned “IP Geo Block” plugin by tokkonopapa. I fixed various issues and improved the overall codebase.
<h4>Features</h4>
<ul>
<li>
Native Geo-Location Provider 
IP Location Block provides <a href="https://iplocationblock.com/codex/native-geo-location-provider/?utm_source=plugin&utm_medium=wporgpage&utm_campaign=readme" rel="nofollow ugc">Native Geo-Location Provider</a> that is faster, more secure and provides the needed precision for matching CITY and STATE besides the standard COUNTRY matching.
</li>
<li>
Privacy by design: 
IP address is always encrypted on recording in logs/cache. Moreover, it can be anonymized and restricted on sending to the 3rd parties such as geolocation APIs or whois service.
</li>
<li>
Immigration control: 
Access to the basic and important entrances into back-end such as <code>wp-comments-post.php</code>, <code>xmlrpc.php</code>, <code>wp-login.php</code>, <code>wp-signup.php</code>, <code>wp-admin/admin.php</code>, <code>wp-admin/admin-ajax.php</code>, <code>wp-admin/admin-post.php</code> will be validated by means of a country code based on IP address. It allows you to configure either whitelist or blacklist to <a href="https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements" title="ISO 3166-1 alpha-2 - Wikipedia" rel="nofollow ugc">specify the countires</a>, <a href="https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing" title="Classless Inter-Domain Routing - Wikipedia" rel="nofollow ugc">CIDR notation</a> for a range of IP addresses and <a href="https://en.wikipedia.org/wiki/Autonomous_system_(Internet)" title="Autonomous system (Internet) - Wikipedia" rel="nofollow ugc">AS number</a> for a group of IP networks.
</li>
<li>
Zero-day Exploit Prevention: 
Unlike other security firewalls based on attack patterns (vectors), the original feature “WordPress Zero-day Exploit Prevention” (WP-ZEP) is focused on patterns of vulnerability. It is simple but still smart and strong enough to block any malicious accesses to <code>wp-admin/*.php</code>, <code>plugins/*.php</code> and <code>themes/*.php</code> even from the permitted countries. It will protect your site against certain types of attack such as CSRF, LFI, SQLi, XSS and so on, even if you have some vulnerable plugins and themes in your site.
</li>
<li>
Guard against login attempts: 
In order to prevent hacking through the login form and XML-RPC by brute-force and the reverse-brute-force attacks, the number of login attempts will be limited per IP address even from the permitted countries.
</li>
<li>
Minimize server load against brute-force attacks: 
You can configure this plugin as a <a href="https://codex.wordpress.org/Must_Use_Plugins" title="Must Use Plugins « WordPress Codex" rel="nofollow ugc">Must Use Plugins</a> so that this plugin can be loaded prior to regular plugins. It can massively <a href="https://iplocationblock.com/codex/validation-timing/" title="Validation timing | IP Location Block" rel="nofollow ugc">reduce the load on server</a>.
</li>
<li>
Prevent malicious down/uploading: 
A malicious request such as exposing <code>wp-config.php</code> or uploading malwares via vulnerable plugins/themes can be blocked.
</li>
<li>
Block badly-behaved bots and crawlers: 
A simple logic may help to reduce the number of rogue bots and crawlers scraping your site.
</li>
<li>
Support of BuddyPress and bbPress: 
You can configure this plugin so that a registered user can login as a membership from anywhere, while a request such as a new user registration, lost password, creating a new topic and subscribing comment can be blocked by country. It is suitable for <a href="https://wordpress.org/plugins/buddypress/" title="BuddyPress — WordPress Plugins" rel="ugc">BuddyPress</a> and <a href="https://wordpress.org/plugins/bbpress/" title="WordPress › bbPress « WordPress Plugins" rel="ugc">bbPress</a> to help reducing spams.
</li>
<li>
Referrer suppressor for external links: 
When you click an external hyperlink on admin screens, http referrer will be eliminated to hide a footprint of your site.
</li>
<li>
Multiple source of IP Geolocation databases: 
Besides the <a href="https://iplocationblock.com/codex/native-geo-location-provider/?utm_source=plugin&utm_medium=wporgpage&utm_campaign=readme" rel="nofollow ugc">Native Geo-Location provider</a>, this plugin supports <a href="https://www.maxmind.com" title="MaxMind - IP Geolocation and Online Fraud Prevention" rel="nofollow ugc">MaxMind GeoLite2 free databases</a> and <a href="https://www.ip2location.com/" title="IP Address Geolocation to Identify Website Visitor's Geographical Location" rel="nofollow ugc">IP2Location LITE databases</a>. Also free Geolocation REST APIs and whois information can be available for audit purposes. 
Father more, <a href="https://iplocationblock.com/cloudflare-cloudfront-api-class-library/" title="CloudFlare & CloudFront API class library | IP Location Block" rel="nofollow ugc">dedicated API class libraries</a> can be installed for CloudFlare and CloudFront as a reverse proxy service.
</li>
<li>
Customizing response: 
HTTP response code can be selectable as <code>403 Forbidden</code> to deny access pages, <code>404 Not Found</code> to hide pages or even <code>200 OK</code> to redirect to the top page. 
You can also have a human friendly page (like <code>404.php</code>) in your parent/child theme template directory to fit your site design.
</li>
<li>
Validation logs: 
Validation logs for useful information to audit attack patterns can be manageable.
</li>
<li>
Cooperation with full spec security plugin: 
This plugin is lite enough to be able to cooperate with other full spec security plugin such as <a href="https://wordpress.org/plugins/wordfence/" title="Wordfence Security — WordPress Plugins" rel="ugc">Wordfence Security</a>. See <a href="https://iplocationblock.com/codex/page-speed-performance/" title="Page speed performance | IP Location Block" rel="nofollow ugc">this report</a> about page speed performance.
</li>
<li>
Extendability: 
You can customize the behavior of this plugin via <code>add_filter()</code> with <a href="https://iplocationblock.com/codex/" title="Codex | IP Location Block" rel="nofollow ugc">pre-defined filter hook</a>. See various use cases in <a href="https://iplocationblock.com/codex/example-use-cases-for-the-developer-hooks/" rel="nofollow ugc">samples.php</a> bundled within this package. 
You can also get the extension <a href="https://github.com/ddur/WordPress-IP-Geo-Allow" title="GitHub - ddur/WordPress-IP-Geo-Allow: WordPress Plugin Exension for WordPress-IP-Geo-Block Plugin" rel="nofollow ugc">IP Geo Allow</a> by <a href="https://github.com/ddur" title="ddur (Dragan) - GitHub" rel="nofollow ugc">Dragan</a>. It makes admin screens strictly private with more flexible way than specifying IP addresses.
</li>
<li>
Self blocking prevention and easy rescue: 
Website owners do not prefer themselves to be blocked. This plugin prevents such a sad thing unless you force it. And futhermore, if such a situation occurs, you can <a href="https://iplocationblock.com/codex/what-should-i-do-when-im-locked-out/" title="What should I do when I'm locked out? | IP Location Block" rel="nofollow ugc">rescue yourself</a> easily.
</li>
<li>
Clean uninstallation: 
Nothing is left in your precious mySQL database after uninstallation. So you can feel free to install and activate to make a trial of this plugin’s functionality.
