User IP Address to Hostname Mapping

Introduction

Configure ip-to-hostname.map to map user IP addresses to hostnames.

warning

Apply the configurations shown in the Open iT Core Server.

Open ip-to-hostname.map in the Configuration directory, which is by default in C:\Program Files\OpeniT\Core\Configuration.

Notice that it contains instructions on how to edit the file.
Specify IP addresses with the following syntax:
Mapping Syntax
```
MAP: <host_name>    
<IP_address1>      
<IP_address2>  
```
Empty lines are allowed — any line beginning with # as the first non-whitespace character is considered a comment. Globbing is also supported, allowing you to use several globbing patterns; however, remember that they are slower than exact matches. To make your mapping files more effective and efficient, refer to the Optimizing Rules to Speed Up Rename or Mapping page.

In the mapping file, entries are case-insensitive, meaning that capitalization variations, such as 'Host' and 'host', will be recognized as identical. Also, note that leading and trailing spaces are removed from entries.
Example
```
MAP: desktop123win   
10.124.113.250
10.56.43.78
10.214.139.109
```
This example maps 10.124.113.250, 10.56.43.78, and 10.214.139.109 to desktop123win hostname.

You can also include custom configurations in this mapping file, such as default mapping, setting date limits on specific mapping entries, or creating nested maps.
Save the changes.

Open ip-to-hostname.map in the etc directory, which is by default in /var/opt/openit/etc.
