In this guide, you add IP addresses to a subnet by hand or from a CSV file, and you download all IP allocations as a CSV file. ITVA shows the IP addresses that you add with the source **Manual**.

ITVA can also add IP addresses for you, from live data on your network. See [Sync DHCP leases](https://www.itva.com/docs/ipam/sync-dhcp-leases) and [Sync DNS records](https://www.itva.com/docs/ipam/sync-dns-records).

## Before you begin

- You have permission to manage IP allocations and to view subnets.
- The subnet for the IP addresses is in your inventory. See [Manage subnets](https://www.itva.com/docs/ipam/manage-subnets).

## Add an IP address

1. In the portal, go to **Inventory** > **IP Allocations**.
2. Select **New IP Address**.
3. In **IP Address**, enter the address. For example, `10.20.0.15`.
4. In **Subnet**, select the subnet that contains the address.
5. Optional: enter a **MAC Address** and a **Name**.
6. Select **Save**.

The IP address must be in the subnet that you select. Each IP address can be in a subnet only one time.

To change an IP address later, open it and select **Edit**.

## Import IP addresses from a CSV file

1. Go to **Inventory** > **IP Allocations**.
2. Open the menu next to **New IP Address**.
3. Select **Bulk Import**.
4. Make a CSV file with the columns `ip_address`, `name`, and `subnet`. Put one IP address on each row.
5. Select the CSV file.
6. Select **Save**.

`ip-addresses.csv`

```
ip_address,name,subnet
10.20.0.15,printer-floor-2,10.20.0.0/24
10.20.0.16,badge-reader-lobby,10.20.0.0/24
```

The `subnet` value must be the exact CIDR of a subnet in your inventory. The CSV file has no MAC address column. To add a MAC address, edit the IP address after the import.

## Download IP allocations as a CSV file

1. Go to **Inventory** > **IP Allocations**.
2. Select **Download CSV**.

ITVA makes the report and then downloads it. The file is named `<DATE>_ipam_ip_addresses.csv` and has the columns `IP_ADDRESS`, `DESCRIPTION`, `SUBNET`, `MAC_ADDRESS`, and `SOURCE`. It includes IP addresses from all sources.

## Check that it worked

1. Go to **Inventory** > **IP Allocations**.
2. In the search box, enter the IP address or name.
3. Make sure that the IP address shows with the source **Manual**.
4. Open the IP address.

The **ARP Entries** and **MAC Entries** cards show live data from your network for this IP address. ARP entries show which devices have this IP address in their ARP table, and with which MAC address. MAC entries show the switch and interface where that MAC address is connected. The cards are empty until you sync ARP and MAC entries. See [Sync ARP and MAC entries](https://www.itva.com/docs/ipam/sync-arp-and-mac-entries).
