# Mapping Hostnames to a Group

# Introduction

Configure license-host-mapping to map hostnames to a group.

Apply the configurations shown in the Open iT server.

Open license-host-mapping 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 host names with the following syntax:
```
MAP: HostGroupName
Hostname1
Hostname2
```
Empty lines are allowed — any line beginning with # as the first non-white character is considered a comment. Globbing is also supported.
Example
```
MAP: HostGroup1    
Host1028
Host0232
```
This example maps Host1028 and Host0232 to HostGroup1.
Save the changes.
