# DNS Hostname

## Introduction

DNS Hostnames are a feature of products, which allow to create a dynamic subdomain automatically in the desired format when the hosting instance is ordered.

## Configuration

The DNS Hostname can be configured for each product individually. You have to configure the format and the domain, which must already exist in the hostware domain portfolio and must be connected to any module or DNS Host.

You can also define a delay, which will be used in between the hostname creation and the hosting installation. If you enter "5 minutes", the dns hostname will be created and 5 minutes after that the hosting will be installed.

You have to select the module field, if the generated dns hostname should be passed to the module. 

hostware will use the IP address of the hosting (if IPAM is enabled) or the IP of the host.
