# Subnet

## IP Plan Module

To start with the IP Plan, you have to enter your subnets. Press **Create Subnet** in the module **Network - Subnet**. By clicking the **Create Subnet** button, user are able to set a subnet. Subsequently after creating a subnet, clicking the **Devices outside of defined subnets** button, will list all devices and show, which ones fall into the set subnets and which ones do not. Those that don’t are makred red, while those that do are black.

Legend:

- IP in ***Green***: The hardware (IP address) is online
- IP in ***Blue***: The Agent has reported the IP recently
- IP in ***Gray***: The hardware has been created manually. e.g. none Windows Machine
- IP in ***Red***: The hardware has been offline for a while. The hardware probably doesn't exist anymore. So don't trust the IP address since it could be outdated.
- IP in ***Black***: Default Gateway
- ***Dark gray*** background: This IP is covered by a **[DHCP scope](https://docs.xeox.com/network/tPRW5EPGgdoSjxsT2bc6ae/dhcp-scope/9M7ju4rgzYHm19w6NUcBEa)**

You are additionally able to manually add an entry to a specific IP in the subnet, by clicking on the entry in the table and either selecting hardware, adding new hardware, determine NAT/ACL. You are also able to enter comments for this entry, wheter it’s a manual or automatic one.

## Subnet Values for Software Rollout

When creating subnets you have the possibility to add **configuration variables** which can be referenced in some automation actions.

To use the configuration variables, the following syntax must be used: **$\[Configuration name\]**

```

http://$nasip/$naspublicpath/install.exe
```
