Sometimes you need to reserve IP to some devices like printers, camera, linux machines etc.<br />In this case, first you need to find MAC Address of that device and define values in that particular subnet.<br />For example, Printer with <b>00:DD:HD:66:55:9B</b> MAC Address has to be assigned with 192.168.100.50 IP. For this, you need to add code like below to that subnet.</div>

<span style="color: #222222; font-family: Trebuchet, Trebuchet MS, Arial, Verdana, sans-serif; font-size: large;"><span style="line-height: 30px;">Most users of Usermin are sysadmins looking for a simple webmail interface to offer their customers. Unlike most other webmail solutions, it can be used to change passwords, read email with no additional servers installed (like IMAP or POP3), and setup users' Procmail configurations for forwarding, spam filtering and autoreponders.</span></span></div>
<div>
<span style="color: #222222; font-family: Trebuchet, Trebuchet MS, Arial, Verdana, sans-serif; font-size: large;"><span style="line-height: 30px;">Usermin also provides web interfaces for viewing and managing data in MySQL and PostgreSQL databases, editing Apache .htaccess configuration files, and running commands on the server. The administrator has full control over which of these modules are available to users.</span></span></div>
